Isle Tower lies on the right bank of the River Nith a half-mile (1 km) southeast of Ellisland Farm, 1¼ miles (2 km) south of Dalswinton and 5 miles (8 km) northwest of Dumfries. Comprising three storeys and an attic, the tower was built in 1587 on the site of an earlier structure for John Ferguson of Isle. The property features crow-stepped gables together with stumpy turrets, which are corbelled out at the top of the northeast and southwest corners.
The tower is accessed via a fine iron yett from the mid-18th whitewashed house which is attached to the south side of the tower. Another wing was added on the west side of the tower in 1806. Both house and tower were modified by architects Peddie and Kinnear in the late 19th century, who added Neo-Jacobean details inside and out. It is thought poet Robert Burns may have used the tower when he farmed at Ellisland.
The property remains occupied.
