St Michael's Mount (Cornish:Karrek Loos yn Koos,[1] meaning "hoar rock in woodland")[2] is atidal island inMount's Bay nearPenzance,Cornwall, England, United Kingdom. The island is acivil parish and is linked to the town ofMarazion by acauseway of granitesetts, passable (as is the beach) between mid-tide and low water. It is managed by theNational Trust, and the castle and chapel have been the home of theSt Aubyn family since around 1650.
Historically, St Michael's Mount was an English counterpart ofMont-Saint-Michel inNormandy, France, which is also a tidal island, and has a similar conical shape, though Mont-Saint-Michel is much taller.[3]
St Michael's Mount is one of 43 unbridged tidal islands accessible by foot from mainlandBritain. Part of the island was designated as aSite of Special Scientific Interest in 1995 for itsgeology. Sea height can vary by up to around 5 metres (16 ft) between low and high tide.[4]
ItsCornish language name—literally, "the grey rock in a wood"—may represent afolk memory of a time before Mount's Bay was flooded, indicating a description of the mount set in woodland. Remains of ancient trees uncovered by storms have been seen at low tides in Mount's Bay[5] which was submerged in 1700 BC.[6]
There is evidence of people living in the area during theNeolithic between around 4000 and 2500 BC. The key discovery was of a leaf-shapedflintarrowhead in a shallow pit on the lower eastern slope, now part of the gardens. Other pieces of flint have been found, and at least two could beMesolithic (about 8000 to 4000 BC).[7] During the early Mesolithic, Britain was still attached to mainland Europe across the southern North Sea between Kent and East Yorkshire (seeDoggerland) but by the Neolithic, because of rising sea level, had become an island.Archaeologist andprehistorianCaroline Malone has noted that during the Late Mesolithic theBritish Isles were something of a "technological backwater" in European terms, still living as ahunter-gatherer society whilst most of southern Europe had already taken upagriculture and sedentary living.[8] The mount was then probably an area of dry ground surrounded by a marshy forest. Any Neolithic or Mesolithic camps are likely to have been destroyed by the later extensive building operations, but it is reasonable to expect the mount to have supported a seasonal or short-term camp.[7]
None of the flints so far recovered can be positively dated to theBronze Age (c. 2500 to 800 BC), although any summit cairns would have most likely been destroyed when the castle was built.Radiocarbon dating established the submerging of the hazel wood at about 1700 BC.[6] Ahoard ofcopper weapons, once thought to have been found on the mount, are now thought to have been found on nearbyMarazion Marsh. Defensive stony banks on the north-eastern slopes are likely to date to the early 1st millennium BC, and are considered to be acliff castle.[7] The mount is one of several candidates for the island ofIctis, described as atin trading centre in theBibliotheca historica of theSicilian-Greek historianDiodorus Siculus, writing in the first century BC.[6][9]


St Michael's Mount may have been the site of a monastery from the 8th to the early 11th centuries.Edward the Confessor gave the site to theBenedictine order ofMont-Saint-Michel.[10][11] In 967 ADKing Edgar granted to Wulfnoth Rumuncant land in theCharter of Lesneague and Pennarth. Lesneague, together withTraboe, was later granted to theBenedictine monks ofSt Michael's Mount byRobert Count of Mortain.[12] It was apriory of that Mont-Saint-Michel until the dissolution of thealien houses as a side-effect of thewar in France byHenry V. Subsequently, it ceased to be a priory, but was reduced to being a secular chapel which was given to the Abbess and Convent ofSyon atIsleworth,Middlesex, in 1424.[13] Thus ended its association with Mont-Saint-Michel,[10][14] and any connection withLooe Island (dedicated to theArchangel Michael). It was a destination forpilgrims, whose devotions were encouraged by anindulgence granted byPope Gregory VII in the 11th century.[15] The earliest buildings on the summit, including a castle, date to the 12th century.[7][16]
Sir Henry de la Pomeroy captured the Mount in 1193, on behalf of PrinceJohn, in the reign ofRichard I,[17] the leader of the previous occupants having 'died of fright' upon learning rumours of Richard's release from captivity.[18] Themonastic buildings were built during the 12th century. Various sources state that theearthquake of 1275 destroyed the originalPriory church,[19] although this may be a misunderstanding of the term "St Michael's on the Mount" which referred to the church of St Michael atopGlastonbury Tor.[20]Syon Abbey, a monastery of theBridgettine Order, acquired the Mount in 1424.[21] Some 20 years later the Mount was granted byHenry VI toKing's College, Cambridge on its foundation.[22] However, whenEdward IV took the throne during theWars of the Roses, the Mount was returned to the Syon Abbey in 1462.[22][23]
John de Vere, 13th Earl of Oxford, seized and held it during a siege of 23 weeks against 6,000 of Edward IV's troops in 1473–1474.Perkin Warbeck, apretender to theEnglish throne, occupied the Mount in 1497. SirHumphrey Arundell, Governor of St Michael's Mount, led thePrayer Book Rebellion of 1549. During the reign ofElizabeth I, it was given toRobert Cecil, 1st Earl of Salisbury, by whose son it was sold to SirFrancis Bassett. During theCivil War, Sir Arthur Bassett, brother of Sir Francis, held the Mount against the Parliament until July 1646.[15]
The Mount was sold in 1659 to ColonelJohn St Aubyn.[15] As of 2024[update], his descendants, theLords St Levan, remain seated at St Michael's Mount.[24]
Little is known about the village before the beginning of the 18th century, save that there were a few fishermen's cottages and monastic cottages. After improvements to the harbour in 1727, St Michael's Mount became a flourishing seaport.
The1755 Lisbon earthquake caused atsunami to strike theCornish coast over 1,000 miles (1,600 km) away. The sea rose six feet (2 m) in 10 minutes at St Michael's Mount, ebbed at the same rate, and continued to rise and fall for five hours. The 19th-century French writerArnold Boscowitz claimed that "great loss of life and property occurred upon the coasts of Cornwall."[25]


By 1811, there were 53 houses and four streets. The pier was extended in 1821[26] and the population peaked in the same year, when the island had 221 people. There were three schools, aWesleyan chapel, and three public houses, mostly used by visiting sailors. Following major improvements to nearbyPenzance harbour, and the extension of the railway to Penzance in 1852, the village went into decline, and many of the houses and other buildings were demolished.
During the 18th and 19th centuries, the structure of the castle wasromanticised.[16] In the late 19th century, the remains of ananchorite were discovered in a tomb within the domesticchapel.[27]
A short, undergroundnarrow gaugerailway was constructed in about 1900. It was used to bring goods up to the castle and take away rubbish. In 2018, the tramway was reported as being "still in regular use, perhaps not every day",[28] and is not open to the general public, although a small stretch is visible at the harbour. It is Britain's last functionally operational4 ft 6 in (1,372 mm) railway.[29][30]
Some sources, including in theBritish industrial narrow gauge railways, alist of track gauges and, in 2018, on an information board near the line, suggest a different gauge of2 ft 5 in (737 mm)[31] whileThe Railway Magazine says it has a gauge of2 ft 5+1⁄2 in (750 mm).[32]
The Mount was fortified inWorld War II, during theinvasion crisis of 1940–1941. Threepillboxes can be seen to this day.[33] After the war, the decommissioned battleshipHMS Warspite was beached near the mount, and was scrapped in place after attempts to refloat the wreck failed.
Sixty-five years after the Second World War, it was suggested based on interviews with contemporaries that the formerNazi Foreign Minister and one-time ambassador to London,Joachim von Ribbentrop, had intended to live at the mount after the planned German conquest. Archived documents revealed that during his time in Britain in the 1930s, when he had proposed an alliance with Nazi Germany, von Ribbentrop frequently visited Cornwall.[34]
In 1954, Francis Cecil St Aubyn, 3rdBaron St Levan, gave most of St Michael's Mount to theNational Trust, together with a largeendowment fund.[24] TheSt Aubyn family retained a 999-year lease to inhabit the castle and a licence to manage the public viewing of its historic rooms, managed in conjunction with the National Trust.[24]

Thechapel ofSt Michael, a 15th-century building, has anembattled tower, one angle of which is a smallturret, which served for the guidance of ships.[15] The chapel isextra-diocesan and continues to serve theOrder of St John[37] by permission ofLord St Levan. Chapel Rock, on the beach, marks the site of a shrine dedicated to theVirgin Mary, where pilgrims paused to worship before ascending the mount. Many antiquities, comprising plate armour, paintings and furniture, are preserved at the castle. Several houses are built on the hillside facingMarazion,[15] and a spring provides a natural flow of water. There is a row of eight houses at the back of the present village; built in 1885, they are known as Elizabeth Terrace. Some of the houses are occupied by staff working in the castle and elsewhere on the island. The mount's cemetery (currently no public access) contains the graves of former residents of the island and several drowned sailors. There are also buildings that were formerly the steward's house, a changing-room for bathers, the stables, the laundry, a barge house, asail loft (now a restaurant), and two former inns. A formerbowling green adjoins one of the buildings. The population of this parish in 2011 was 35.[38]
The harbour, enlarged in 1823 to accommodate vessels of up to 500 tonnes deadweight, has apier dating back to the 15th century which has also been renovated.Queen Victoria disembarked from theroyal yacht at St Michael's Mount in 1846, and a brass inlay of her footstep can be seen at the top of the landing stage. KingEdward VII's footstep is also visible near the bowling green. In 1967Queen Elizabeth the Queen Mother entered the harbour in apinnace from theroyal yachtBritannia.
The islandunderground railway is used to transport goods from the harbour to the castle. It was built by miners around 1900, replacing the pack horses which had previously been used. Its steep gradient renders it unsafe for passenger use; thus the National Trust has made it out-of-bounds for public access.
Thecauseway between the mount and Marazion was improved in 1879 by raising it by one foot (30 cm) with sand and stones from the surrounding area.[39] Repairs were completed in March 2016 following damage from the 2014 winter storms.[40] Some studies indicate that any rise in ocean waters as well as existing natural erosion would put some of the Cornwall coast at risk, including St Michael's Mount.[41]

Until recent times, both the mount and the town of Marazion formed part of theparish ofSt Hilary.[11] St Michael's Mount forms its owncivil parish for local government purposes. Currently, this takes the form of a parish meeting as opposed to a parish council (that is, a yearly meeting of electors that does not elect councillors).Lord St Levan currently chairs the St Michael's Mount parish meeting.
The rock exposures around St Michael's Mount provide an opportunity to see many features of thegeology of Cornwall in a single locality.[42] The mount is made of the uppermost part of agranite intrusion intometamorphosedDevonianmudstones orpelites. The granite is itself mineralised with a well-developed sheetedgreisenvein system. Due to itsgeology, the island's seaward side has been designated aSite of Special Scientific Interest since 1995.[43][44]
There are two types ofgranite visible on the mount. Most of the intrusion is atourmalinemuscovite granite which is variablyporphyritic.[42] This is separated from abiotite muscovite granite bypegmatites.[42]
Originally laid down as mudstones thesepelites were regionally metamorphosed and deformed (mainlyfolded here) by theVariscan orogeny.[42] They were then affected by theintrusion of the granite, which caused further contact metamorphism, locally forming ahornfels, andtinmineralisation.[42]
The best developed mineralisation is found within the uppermost part of the granite itself in the form of sheeted greisen veins. These steep W-E trending veins are thought to have formed byhydraulic fracturing,[42] when the fluid pressure at the top of the granite reached a critical level. The granite was fractured and the fluids altered the granite by replacingfeldspars withquartz and muscovite. The fluids were also rich inboron,tin andtungsten, and tourmaline,wolframite andcassiterite are common in the greisen veins. As the area cooled, the veins became open to fluids from the surroundingcountry rock and these deposited sulphides, e.g.chalcopyrite andstannite. Greisen veins are also locally developed within the pelites.[citation needed]
In prehistoric times, St Michael's Mount may have been a port for thetin trade, andGavin de Beer made a case for it to be identified with the "tin port"Ictis/Ictin mentioned byPosidonius.[6]
There are popular claims of a tradition that the ArchangelMichael appeared before local fishermen on the mount in the 5th century AD.[45] But in fact this is a modern myth. The earliest appearance of it is in a version byJohn Mirk, copying details of the medieval legend for Mont-Saint-Michel from theGolden Legend.[46] The folk-story was examined and found to be based on a 15th-century misunderstanding by Max Muller.
The chroniclerJohn of Worcester[47] relates under the year 1099, that St Michael's Mount was located five or six miles (10 km) from the sea, enclosed in a thick wood, but that on the third day of November the sea overflowed the land, destroying many towns and drowned many people as well as innumerable oxen and sheep; theAnglo-Saxon Chronicle records under the date 11 November 1099, "The sea-flood sprung up to such a height, and did so much harm, as no man remembered that it ever did before".[48] The Cornish legend ofLyonesse, an ancient kingdom said to have extended fromPenwith toward theIsles of Scilly, also talks of land being inundated by the sea.
One of the earliest references to the mount (originally named "Dynsol" or "Dinsul"), was in the mid 11th century when it was "Sanctus Michael beside the sea".[49][50]
In the 1600s,John Milton used the Mount as the setting for the finale of what was once one of the most famous poems in English literature, his "Lycidas", which drew on the traditional sea-lore that had it that the archangel Michael sat in a great stone chair at the top of the Mount, seeing far over the sea and thus protecting England. In the mid-1850s the poem's scenes of the drowning of Lycidas, in the seas below the Mount, were illustrated in engravings and paintings byJ. M. W. Turner. The poem drew together various traditions from the Bible, classical mythology and local folklore to offer an elegy for the pagan world that had faded away.[citation needed]
According to legend, the island was once home to a giant namedCormoran, who lived on the Mount and stole livestock from local farmers.[51][52] A reward was offered to stop Cormoran and a boy named Jack put himself forward, killing Cormoran by trapping him in a concealed pit and burying him there.[51] When he returned home, the elders in the village gave him a hero's welcome, and henceforth, called him "Jack the Giant Killer".[51]
The mount has featured in a number of films, including the 1979 filmDracula, where it was prominently featured as the exterior ofCastle Dracula.[53]
