The Broch of Culswick (also Culswick Broch) is an unexcavated coastal broch in the Shetland Islands of Scotland (grid reference HU25384481). It has good views all around, including Foula and Vaila isles, and Fitful Head and Fair Isle in the south. The broch stands on the top of a rock platform and is about 3 metres high at its tallest point. Much rubble has fallen into the centre. This broch has a massive triangular lintel stone over the entrance, which is partly filled with rubble. A drawing by George Low in 1774 reveals that the structure survived very well at that date.
