ABERNETHY, a town of Scotland, in Perthshire, situated at a short distance to the southward of the right bank of the river Tay, a little above the mouth of the Earne. It is of very ancient date, and is said to have been the seat of the Pictish kings; and there are some uncertain traditions of its existence prior to this period. It is distinguished by a curious piece of antiquity; namely, a circular tower 74 feet high and 16 in diameter, consisting of 64 courses of hewn stone. It continued long to be the see of an archbishop, which was afterwards transferred to St Andrews. The inhabitants are engaged in the manufacture of linen. The population in 1821 was 1701. 7 miles from Perth.
