Harden Castle is a 16th-century tower house, about 3.5 miles (5.6 km) west of Hawick, Scottish Borders.
[3] The castle, which succeeds an earlier tower which was destroyed about 1590,[3] belonged to the Homes, but was purchased by the Scotts in 1501.
[3] The castle incorporates a three-storey tower house; it was extended between 1680 and 1690, with internal changes also,[3] and again when it was reoccupied.
[4] In the grounds there is a bowling green, possibly dating from the 17th century, to the west of the house.
And there is a sundial, originally at Dryburgh House, 4 feet (1.2 m) high, with a square dial stone, a twisted shaft, and a moulded base.
