Broch of Culswick
United Kingdom
The 186th tallest tower in the world
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. Drawings by Low in 1774 and Skene in 1805 reveal that the structure survived very well up to those dates.
