Clackmannan Tower is located on King's Seat Hill, on the western edge of the town of Clackmannan in the Scottish county of Clackmannanshire. The tower is at an elevation of above sea level, with views of the River Forth to the south and the Ochil Hills to the north. The tower is largely still intact from its medieval days, including the roof, although part of the eastern wall was reconstructed following a collapse in 1950. The building is L-shaped, with five storeys. The original part of the building is on the north, and the slightly higher 1500s wing to the south, using cut blocks of pink sandstone. The newer section features a fireplace on the second floor, typical of its period. Gardens and an area probably once used as a bowling green are situated to the south of the tower, while a large platform is on the northern side.
