Broch of Culswick

The Broch of Culswick is an Iron Age stone fortification situated on a coastal knoll in the Shetland Islands. The circular structure with double walls contains three internal passage galleries and features a triangular lintel at its entrance.

The structure was built during the Iron Age as a defensive fortification and remained substantially intact until the early 19th century. Historical drawings from that period document the original three-story construction before later decay occurred.

The broch reflects how Iron Age builders created functional spaces within double walls and integrated passage systems into the structure. This design allowed inhabitants to combine defensive shelter and storage within a compact circular form.

Access is via a track from Culswick hamlet that passes by Loch of Sotersta and ascends steeply in the final section. Visitors should wear sturdy footwear and prepare for changeable weather conditions typical of the island setting.

From its elevated position, the ruin offers views across the water toward the islands of Foula and Vaila, as well as toward Fitful Head and Fair Isle. This vantage point made it a strategic lookout location for ancient inhabitants.
