Drummond Castle is situated in Perthshire, Scotland. The castle is famous for its gardens, described by Historic Environment Scotland as "the finest example of formal terraced gardens in Scotland." It is located in the parish of Muthill, 4 kilometers (2.5 mi) south of Crieff.
The castle is on a prominent rocky spine known as Gask Ridge, a geographical feature that extends for several miles across Perthshire. The tower house, or keep, is no longer used as a residence. Standing between the tower house and the edge of the ridge, it was originally meant to control access to the courtyard behind it, which offers a beautiful view of the formal gardens. The French gardens are situated to the south of the castle, on its rocky outcrop.
