Lochwood Tower, also known as Lochwood Castle, is a ruined 16th-century L-plan tower house situated in Annandale (Valley of the River Annan) about 6 miles (9.7 km) south of the town of Moffat in the modern county of Dumfries and Galloway, Scotland.

[1] They described it as 'a fair large tower, able to lodge all our company safely, with a barmkin, hall, kitchen and stables, all within the barmkin…'.

[5] It was rebuilt, and James VI of Scotland and Ludovic Stewart, 2nd Duke of Lennox stayed on 11 October 1592.

[1] Lochwood Tower, a Motte-and-bailey castle overlain by a later stone castle, lies on the east of a promontory about 600 metres (2,000 ft) long and 400 metres (1,300 ft) wide, which thrusts northwards into an area of largely-unreclaimed moss.

[1] On the north was a hillock 'apparently in part artificial' named 'The Mount', a circular double-terraced motte with ramparts, apparently a Norman predecessor of the stone tower.
