Abernethy is a village in Perth and Kinross, Scotland, situated south-east of Perth. It has one of Scotland's two surviving Irish-style round towers (the other is at Brechin, Angus; both are in the care of Historic Scotland). The tower stands high, and it is possible to climb to the top, using a modern metal spiral staircase (the tower originally had several wooden floors linked by ladders). The tower was evidently built in two stages (shown by a change in the masonry), and probably dates to the 11th-early 12th centuries.
