Castle Kennedy is a ruined 17th-century tower house, about 3 miles (4.8 km) east of Stranraer, Dumfries and Galloway, Scotland, around 0.5 miles (0.8 km) north of the village of Castle Kennedy.
After a brief period in the hands of the Hamiltons of Bargany the property passed to the Dalrymples of Stair around 1677.
From the main entrance a vaulted passage runs through the basement;[1] it communicated with a newel-stair in the south west re-entrant turret.
[1] It is thought that the public rooms were situated within the main block, which had a single large chamber at each level.
There is no evidence of any enclosure; there is a walled garden to the south which dates from the 18th century.
