What Dunglass Castle looked like in its prime.

Perched on a rocky riverside cliff above the River Clyde, the castle originally presented a continuous stone curtain wall rising straight from the rock face to about 7–8 metres, punctuated by a stout cylindrical tower at a corner and a small conical dovecot set into the south wall. A riverside landing sits below the walls, and corbels along the south face indicate a former projecting wooden hoarding above the wall; roofs and internal ranges would have filled the enclosure when complete.

Its story

The story of Dunglass Castle.

Dunglass Castle sits on a rocky cliff overlooking the River Clyde in West Dunbartonshire, a 14th-century castle now ruinous. It was attacked by Lord Fleming's soldiers from Dumbarton Castle in November 1568, and again in February 1569, when they were repulsed and Lord Fleming's half-brother was captured.

A large section of boundary wall still stands roughly seven to eight metres high, mixing original and newer construction, with a now-ruined conical dovecot on the south wall, a small protected landing place outside it, a dwelling house at the north-west corner possibly dating back to 1590, and a round tower, probably 17th-century, that appears to have been a pigeon house.

In July 1893 the graphic artist Talwin Morris leased the castle and remodelled the interior; a remnant of the Morris interior is held in the West Dunbartonshire Council collection. On the grounds stands the obelisk memorial to Henry Bell, an early steamship pioneer. Designated a Category B listed building in 1971, the ruin is graded at high risk by the Buildings at Risk Register for Scotland.
