Little Cumbrae (Scottish Gaelic: Cumaradh Beag) is an island in the Firth of Clyde, in North Ayrshire, Scotland. It lies south of Great Cumbrae, its larger neighbour. The underlying geology is igneous with limited outcrops of sedimentary rock. Little Cumbrae House is of 20th century construction, although the island has no permanent inhabitation at present, its population having peaked at 23 in the late 19th century. There is a lighthouse on the western coast.
The Cumbraes were one of the remote locations that early Irish monks settled. There are six or more known caves on the island. A submarine passage was said to run from Monks’ Cave (now known as Kings Cave) at Storrils cliff to Kingarth on the Isle of Bute.
Walter Stewart is said to have built a castle or hunting lodge on Little Cumbrae. His son, Robert II spent time there hunting the deer, however the site of the “Auld Castle” is unknown. It was occupied during hunting expeditions by Robert II in 1375 and 1384, and was demolished by Cromwell‘s soldiers in 1653.
Little Cumbrae Castle, a small square keep, was built in the 16th century on Castle Island off Little Cumbrae. It was similarly occupied.
In the early 20th century, under the ownership of Evelyn Stuart Parker, a new ‘mansion house’ was created from the original single storey farmhouse, the gardens were laid out to a plan by Gertrude Jekyll, the renowned garden designer, and substantial repairs were undertaken to the castle and the original lighthouse. The original work commenced in 1913, with subsequent alterations made between 1926 and 1929 when the square tower and top floor were added.
Little Cumbrae is the birthplace of James Archbald, the first mayor of Carbondale, Pennsylvania.
James Ewing built the first Little Cumbrae lighthouse on the top of Lighthouse Hill in 1757. This was the second lighthouse in Scotland. An open coal fire was lit at the top of a circular stone tower. Remains of this old structure can still be seen and are designated a scheduled monument.
The traditional Cumbrae Lighthouse was designed and built in 1793 by Thomas Smith under commission from the Commissioners of the Northern Lights. The lighthouse lies on a broad raised beach on the western shore of the island looking out into the Firth, 0.5 km from the first light. It had a foghorn, slipway, jetty, and boathouse. The original oil lamps were replaced by Argand lamps in 1826. In 1865, the foghorn was installed; the first in Britain. The tower was restored in 1956 and a solar-powered light was installed in 1974. The 1793 tower has been unused since 1997, with the light on a 36-foot (11-metre) hexagonal/cylindrical tower adjacent to the old generator house.
