Pladda (High)

Pladda is a small, teardrop-shaped island about 1.5 km (1 mi) south of Kildonan, off the southern point of the Isle of Arran.

The lighthouse was first lit in October 1790 and joined the lights on the Mull of Kintyre, Cumbrae in the Firth of Clyde, and Copeland light on the Irish coast.

To allow Mariners to distinguish it from the other lights, Pladda had to show a lower light from a small lantern 20 feet below the original one – an arrangement that was soon made permanent and was to operate for more than 100 years.

In 1870 trials were carried out at Pladda with paraffin, a light material oil which now superseded colya, just as that on Joseph Mumi’s recommendation had succeeded sperm oil. In 1874 the Commissioners ordered sirens driven by hot air engines from America. Pladda was about the third station in 1876 to have a fog signal.

In 1901 fixed lights were no longer regarded as suitable for the great landfall and coastal lights and a powerful group flashing light was installed.

Provisions and other light stores were brought to the lighthouse by boatmen permanently attached to the station and they also carried out the reliefs. These attending boats were limited to four visits to the rock per month with two on Sundays to enable the lightkeepers to attend church. All this changed in 1972 with the introduction of the helicopter, which was used to transport the keepers back and forward.

The Station was automated in 1990 and the Lightkeepers withdrawn. The light is now remotely monitored from the Northern Lighthouse Board’s Headquarters in Edinburgh.

The island was sold into private ownership in 1990; in 2022 it was for sael for £350,000. Located on the highest point of the island. Accessible only by boat; there are excellent views from coastal sites throughout the Kildonan area. Site and tower closed.

"The "double lights" were replaced by a powerful flashing system in 1901." (Ref: Wikipedia)
"Made up of three bullseye panels, it was taken out of the tower, but its location is unknown. Reportedly moved to the Arran Heritage Museum."
