A modest baronial mansion and estate of NE Stirling, Leny lies to the north of Kilmahog, 1¼ miles (2 km) northwest of Callander. Leny House began as an L-plan tower house in 1513, was strengthened in 1691 and largely rebuilt 1845-46 by David Bryce (1803-76) as a Jacobean-style mansion. Part of the harled 16th C. original can still be seen on the north side. Bryce first used a round entrance-tower here, which became a familiar feature in his subsequent houses.
Leny was long the property of the Buchanan family, most notable amongst whom was Francis Buchanan (1752 - 1829) who explored NE India, wrote several works of natural history and introduced many unusual plants to the grounds at Leny. An earlier Francis Buchanan was hanged by the Jacobites in 1746 when the Head of Clan Stewart was shot an Leny. The house was restored in 1998 and is now used as a family-run hotel.
The grounds include sundial (c.1630) and a walled-garden dating from the 18th century. The site of the old Leny Castle lies a half-mile (0.8 km) to the southeast next to the A84 Trunk Road.
