Logan Rock, Granite rock formation in Treen, Cornwall.
Logan Rock is a granite formation in Treen, Cornwall, that rests on a natural pivot point on the cliffs above the sea. The stone weighs roughly 65 tons and sits about 30 meters (98 feet) above the water, with its shape allowing the former rocking motion.
In 1824 Lieutenant Hugh Goldsmith and his naval crew pushed the stone into the sea, sparking public outrage. Goldsmith was forced to fund the restoration at his own expense, which required the work of over sixty men.
The name derives from the Cornish word for rocking and describes the traditional movement visitors could cause with slight pressure. Local residents still demonstrate this characteristic to guests, though the original sensitivity was partly lost after the restoration work.
Visitors reach the formation by following marked coastal paths from the parking area in Treen, with the terrain sloping and potentially slippery in wet conditions. The route connects with paths to Penberth and Porthcurno beaches and offers several viewpoints along the way.
Metal attachments from the 1824 restoration remain visible on the surface and show the technique used to move the heavy load. These traces of the reconstruction offer direct evidence of the engineering skills of the time and the public pressure involved.
