Bartiné-Hill is one of a chain of eminences near the Land's End, which command extensive views over the English and Irish Channels. On its summit is an ancient Earth-work, or Hill Castle, (as all these remains with ramparts are called in Cornwall,) consisting of a circular mound or vallum, slightly elevated above the natural soil, and a ditch. It contains a well, now filled up, and the remains of three contiguous circles, of different sizes, the largest being 28 feet across, whilst the whole interior diameter is about 860 feet. Borlase was uncertain whether these small circles were intended for military or religious purposes, but supposed them rather to have been the sepulchres for some of the garrison. I will only observe that a Circle of the same description remains within the area of Caër-Bân, and another at Castle-An-Dinas, in Cornwall: Mr Pennant noticed similar inclosures within the Hill Fortresses of Wales.
