What is recorded here

Castle Semple is a ruined peel tower standing on a rocky islet in Castle Semple Loch, Renfrewshire, built by the Semple family during the 17th century. Robert, 3rd Lord Semple, named it Defender of the Faith while opposing the Scottish Reformation, and the stone walls still hold ornate carvings that hint at quiet domestic life beneath the military purpose. The curved earthen embankment now links the islet to the shore, but the loch remains the castle’s true boundary, and the ruin still faces the water like a guard who never left its post.

Scotland's National Record of the Historic Environment records Castle Semple as No Class (event) (period Unassigned). The official map says its point is accurate as follows: NGR given to the nearest 10m. The record does not by itself mean that the public may enter the place.
