What is recorded here

Thornton Castle stood opposite Innerwick Castle across Thornton Glen until English cannons and gunpowder erased it in September 1547. Tom Trotter rode away after pretending to seek counsel, leaving a small garrison to face four guns and musketeers who blocked the gunloops. The defenders surrendered, the castle was blown up, and no wall now remains for that promise to touch.

Scotland's National Record of the Historic Environment records Thornton Castle as Castle (medieval). 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.

Thornton Castle was built in the late 14th or early 15th century by the Keith family, a prominent Scottish noble lineage. It is remembered as a strategic stronghold in the Scottish Borders, reflecting the turbulent history of the region during the Wars of Scottish Independence and subsequent border conflicts.
