TheShah Mosque (Persian:مسجد شاه,lit. 'Masjed-e Shah'), also officially known as theImam Mosque orImam Khomeini Mosque, is amosque located on the south side ofNaqsh-e Jahan Square inEsfahan, in the province ofIsfahan,Iran. Its construction began in 1611, during theSafavid Empire under the order ofAbbas the Great, and was completedc. 1630.
It is regarded as one of the masterpieces ofPersian architecture in the Islamic era. The mosque is registered, along with theNaghsh-e Jahan Square and other surrounding structures, as aUNESCOWorld Heritage Site.[1] It was added to theIran National Heritage List on 6 January 1932,[citation needed] administered by theCultural Heritage, Handicrafts and Tourism Organization of Iran. The mosque is depicted on thereverse of the Iranian 20,000rials banknote.[2]
In 1598, whenShah Abbas decided to move the capital of his Persian empire from the northwestern city ofQazvin to the central city of Isfahan, he initiated what would become one of the greatest programs in Persian history; the complete remaking of this ancient city. By choosing the central city of Isfahan, fertilized by theZāyandeh River ("thelife-giving river"), lying as an oasis of intense cultivation in the midst of a vast area of arid landscape, he both distanced his capital from any future assaults by Iran's neighboring arch rival, theOttomans, and at the same time gained more control over thePersian Gulf, which had recently become an important trading route for the Dutch and BritishEast India Companies.[3]
Shah Abbas's urban planning focused on two key features: theChahar Bagh avenue, flanked at either side by all the prominent institutions of the city, such as the residences of all foreign dignitaries, and theNaqsh-e Jahan Square ("Exemplar of the World").[4][edition needed] Prior to his ascent to power, Persia had a decentralized power structure, in which different institutions battled for power, including both the military (theQizilbash) and governors of the different provinces making up the empire. Shah Abbas wanted to undermine this political structure, and the recreation of Isfahan, as a grand capital of Persia, was an important step in centralizing the power.[5]
Construction of the Naqsh-e Jahan Square began around 1590.[6] Construction on the Shah Mosque itself, which was part of this project, only began in 1611 (1020AH), possibly due to delays in purchasing the land required.[7] Based on the series of dated inscriptions around the mosque, construction was probably completed around 1630–1 (1040 AH), which is the date of the inscription on the mosque's westerniwan.[8] This indicates that construction finished in the early years of Abbas's successor,Shah Safi.[8][9][10] The alabaster dadoes around the mosque were only added in 1638.[11] The construction was reported to have cost 60,000tomans, reflecting the size of the project.[12]
The name of the architectAli Akbar Isfahani appears in the main foundation inscription of the mosque, located above the doorway of the entrance iwan. The inscription also mentions that the supervisor of the construction was Muhibb 'Ali Beg Lala, who was also a major donor to the mosque. Another architect, Badi al-Zaman-i Tuni, is mentioned as the imperial architect during an account of the land purchases prior to construction. He may have been involved in the early phase of construction, while Ali Akbar most likely completed the project.[13][14] The name of the calligrapherAli Riza (or Ali Reza), who also designed the inscriptions for the nearbyLotfallah Mosque, appears at the end of the same inscription, suggesting he was involved in designing the mosque's epigraphic compositions.[15][14]
Because of the Shah's desire to have the building completed during his lifetime, shortcuts were taken in the construction; for example, the Shah ignored warnings by one of the architects, Abu'l Qāsim, regarding the danger of subsidence in the foundations of the mosque, and he pressed ahead with the construction.[16] The architect proved to be right, as in 1662 the building had to undergo major repairs.[12]
In the years after theIranian Revolution of 1978–1979, the mosque's official name was changed to Imam Khomeini Mosque[9][6] or Imam Mosque, in honour ofRuhollah Khomeini.[17][18]
The latest restoration project on the mosque began in 2010.[19] Damage to the dome was discovered in 2022 due to errors in the work.[20] In June 2024, Iranian officials announced the completion of the restoration work on the dome, including repairs to correct the previous errors.[19] In June 2025, another phase of the restoration was announced and aimed at restoring the tile decoration on the middle portion of the dome, with a budget of over 8.5 billion Iranian rials.[21]
The mosque is integrated with the design of the Naqsh-e Jahan Square. It is entered through a monumentaliwan (a vaulted space open to one side) that is topped by twominarets. The portal is around 27.5 metres (90 ft) tall and the minarets are 33.5 metres (110 ft) tall.[7] The vault inside the iwan is filled with an elaboratemuqarnas (stalactite-like) composition.[22] Because the square is not aligned with theqibla (the direction ofMecca), the mosque's large vestibule makes an approximately 45-degree turn towards the southwest to allow the rest of the building to follow the correct alignment for prayers.[23] ScholarDonald Wilber suggests that this general design choice could have been deliberate: because the prayer hall of the mosque is placed on a different axis, its dome is thus prominently visible from the main square, whereas the dome would have been obscured by the mosque's entrance portal if it had been on the same axis as the square.[24] Aside from this bend, the rest of the mosque's internal layout is highly symmetrical.[23]
The Shah Mosque is said to contain 18 million bricks and 475,000 tiles.[12] The main block of the building measures around 100 by 130 metres (330 by 430 ft).[6] It employs thefour-iwan plan that was common for Iraniancongregational mosques.[15] This had been a regular feature of Iranian mosques since theSeljuk period, when it was introduced into this type of building, notably in the olderJameh Mosque of Isfahan.[25][26] Accordingly, the mosque contains a spacious rectangular courtyard in the center that is surrounded by four monumental iwan portals. The northern iwan opens from the vestibule, the lateral iwans to the east and west lead into domed halls, and the southern iwan leads into the main prayer hall covered by the large dome. The façades that run between these iwans are occupied by two-storyarcades.[23]
In addition to this, the main prayer hall is flanked on either side by two rectangularhypostyle halls withvaulted ceilings, which served as prayer halls in the winter and are entered via smaller vaulted portals.[23] Occupying the two southern corners of the building are two long rectangular courtyard structures which served asmadrasas.[6] An annex is also attached to the east side of the vestibule, consisting of a domed hall followed by another rectangular courtyard structure. This containedlatrines andablutions facilities.[15]
One of the distinctive features of a mosque is the minaret, and the Shah Mosque has four. In addition to the two minarets over the entrance portal, two more minarets flank the iwan leading into the main prayer hall. In Persian mosques, tall minarets were considered unsuitable for thecall to prayer. Instead, architects added an aedicule, known in Persian as aguldasta ("bouquet") for this particular purpose, which in the Shah Mosque stands on top of the west iwan facing the courtyard.[15]
The main prayer hall is covered by a huge dome reaching to a height of 52 metres (171 ft)[27] and a diameter of around 25 metres (82 ft).[9] It has a double-shelled structure, inspired by earlierTimurid domes, with a difference of 14 metres (46 ft) between the two shells. The dome rests on adrum and a sixteen-sided base that transitions to the square hall below.[27] Inside the hall is themihrab, a niche with a large marble tablet 3.0 metres (10 ft) tall and 0.91 metres (3 ft) wide on the southwestern wall, indicating theqibla. Above it, the Shah's men had placed a gold-encrusted cupboard of allow wood. It held two relics: aQuran, said to have been copied byImam Reza, and the bloodstained robe ofImam Hussain. Although never displayed, the robe was said to have magical powers; lifted on the end of a pike in the battle field, the belief was that it could rout an enemy.[28]
The mosque is also a marvel in acoustic engineering, with the echo of the dome allowing for prayer to be heard throughout the mosque.[29]

The mosque employed the newhaft rangi ('seven-colour') style oftilework. Earlier mosques and monuments had made use of tilemosaic, a slow and expensive process where tiny pieces are cut from monochrome tiles and assembled to create intricate designs. In thehaft rangi method, single tiles were painted with multiple colors simultaneously and then fired. This process was cheaper and quicker, while also allowing for a wider range of colors.[12][30] According to 17th-century travelerJean Chardin, the low humidity of the local environment made the colors more vivid and the contrasts between the different patterns stronger than what could be achieved in Europe, where the colors of tiles turned dull and lost their appearance.[31] Still, most contemporary and modern writers regard the tile work of the Shah Mosque as inferior in both quality and beauty to those covering the nearbyLotfallah Mosque, the latter often referred to by contemporary Persian historians, such asIskandar Munshi, as "the mosque of great purity and beauty".[32] The architects also employed a great deal of marble, which they gathered from a marble quarry in nearbyArdestan.[12]
The highest-quality tiles are found on the entrance portal of the mosque, which employ a repertoire of seven colours:dark blue, light blue, white, black, yellow, green and beige. Framing the iwan around its edge is a wide inscription band containing religious texts execute in whitethuluth script on a dark blue ground. In the rest of the mosque, the tiles are predominantly blue, except in the winter prayer halls, which were later redecorated with tiles of yellow-green.[30]
