Irevik (also known asIreviken orIhreviken ) inHangvarsocken 5 kilometres (3 miles) north ofVisby, is a more than 2-kilometre-long (1 mi) section of the Swedish islandGotland's coastline.
There are several settlements fromStone andBronze Ages. There are also remains of ancient castles on the cliffs.
Ihre farm is located at the exit road down to the bay from the country road. The first known owner of the farm was named Hans Eire. His grandson Thomas Ihre moved toLund from Visby to finally become a judge inLinköping.
The Ireviken event was the first of three relatively minorextinction events (the Ireviken,Mulde, andLau events) during theSilurian period. The event is best recorded at Ireviken, Gotland, where over 50% oftrilobite species became extinct.

The bay is framed by high cliffs and the beach is also considered one of Gotland's best beaches.[2]In the middle is a long sandy beach which is one of Gotland's most visited. The river Ireån opens into the bay.[3]
Formerly afishing village, Irevik is mainly a summer cottage area, and nearly 200 cottages are on mature forest sites. The houses have been built for a long time, and the area therefore has a mixed character without a hint of mass-produced cottage area. Although the area is not very large, there are three different entertainment establishments – the Ihrebaden, Ihre farm and Ihre mill.
In the northern part of Irevik lies Sigsarve beach. It is also the starting point of the 28-square-kilometer Hall-Hangvar Nature Reserve, which is Gotland's largest. From Sigsarve beach, the reserve stretches along a 25 km (16 mi) stretch of coastline. In the eastern part of the reserve, on the other side of the road, is Träskmyr moor, the largest preserved moor on Gotland.[4] It is a so-calledagmyr (Swedish for a calcareous bog. There are many unusual flowers in the reserve, such as theFumana or needle sunrose (Fumana procumbens),Euphrasia and alpine key.
According to theKöppen climate classification, Irevik has anoceanic climate. This renders cooler summers and milder winters than most of mainland Sweden. However, in spite of its marine position the climate is very much influenced by continental airflows. The precipitation amount is quite moderated, especially for an oceanic climate, but is relatively consistent throughout the year.
