Scolpaig Tower (also known as Dùn Scolpaig or MacLeod’s Folly) is a Georgian folly located near the village of Scolpaig on the Isle of North Uist in the Outer Hebrides. The name likely derives from the Old Norse scolpvik, or 'Scolp Bay' (a scolp being a large Hebridean vessel, probably relating to the nearby bay where such boats may have landed).
It was built in about 1830 by Dr Alexander MacLeod, who was the factor of the North Uist estate. It was erected to provide employment for the purpose of famine relief. Built over an Iron Age dun on a small islet in Loch Scolpaig, the Gothic-style folly has an octagonal footprint and appears as a two-storey structure surmounted by a crenellated parapet. Today the tower is open to the elements and serves as a nesting place for birds.
