Balhousie Castle, located in Perth, Scotland (on Hay Street, originally a few hundred metres north of the medieval town), was built in the 17th century.

It originally served as the seat of the Earls of Kinnoull, and stood within a walled enclosure containing subsidiary buildings, orchards etc., on a terrace overlooking the North Inch.

After falling into neglect in the early 19th century, the Castle was 'restored' (in fact, virtually rebuilt), and extensively remodelled on a larger scale between 1862 and 1864 in the Scottish Baronial style by the architect David Smart.

The Black Watch Heritage Appeal was launched in September 2009 allowing the regiment to raise in excess of £3.2 million to develop Balhousie Castle to provide a permanent home for the museum and archive of The Black Watch.
