WHAT TO EXPECT
01 / THE STORY
Barr Castle rises almost to its original height on a low ridge south of Lochwinnoch. The isolated tower once stood within a larger household complex. Its courtyard and adjoining buildings have largely vanished, but their traces remain in the ground and masonry.
The Glen family apparently built the tower in the early sixteenth century. The original entrance was at first-floor level. The four-storey tower had two vaulted ground-floor rooms, with the principal hall above.
Look at the south wall for the sloping roofline of a lost adjoining building. A wall fragment near the entrance is another clue to the former complex. A dressed stone around 90 metres north may be an old gatepost, although this identification is uncertain.
Barr later passed to the Hamiltons of Ferguslie. Substantial alterations in the late seventeenth century added living space and moved the entrance down to ground level. Narrow openings and gunports survive beside windows from later changes.

01 / THE STORY CONTINUES
A nineteenth-century account already described the tower without a roof. Today it is a protected monument on private land. Its interior is secured by a locked door, so plan to appreciate the exterior from a lawful viewpoint.
03 / MOMENTS IN STONE
The Glens apparently build the tower. The original entrance stood above ground level.
The Hamiltons remodel and enlarge the residence. Masonry scars reveal buildings no longer standing.
The tower is already described as roofless. A stone to the north might mark the former enclosure; its interpretation remains uncertain.
