Description
Old Harbour in Portencross is likely a late medieval structure for the south harbour and a 19th-century addition for the north harbour.
The south harbour features a curved drystone quay wall, constructed with large blocks that define the edge of the quay, situated on a rock outcrop. The north harbour consists of two angled mortared stone quay walls that create a basin suitable for small boats.
