Hills Tower is a sixteenth-century square tower house, with an adjoining eighteenth-century wing, near Dumfries in Scotland. Originally built around 1527 for Edward Maxwell, who had purchased the estate from James Douglas of Drumlanrig, it was improved in the later sixteenth century by his grandson, also Edward Maxwell. In 1721, another Edward Maxwell had a two-storey Georgian wing added to the tower's east side, using stone taken from older buildings nearby, and incorporating armorial panels celebrating members of the Maxwell family.
The tower is unusual in that it has retained its original barmkin walls and their gatehouse. It eventually passed by marriage to the McCullochs of Ardwall, who still retained ownership of it as of 1994. It is still inhabited, and in 1971 the tower, along with the walls and gatehouse, was designated a Category A listed building.
