Seacliff Harbour is a sheltered spot accessible through a narrow channel, all blasted out of the red sandstone cliffs. This was constructed in 1890 by Andrew Laidlay, the then laird, who used a steam engine and compressed air to cut the stone. It was once home to boats owned by fishermen and landowners but today it is rarely used by boats and more for diving and dive training. The entrance measures just three metres across and it is the smallest harbour in the UK.
