The Wemyss Caves are a nationally important heritage site under threat from coastal erosion, structural instability and vandalism. They are a scheduled ancient monument.

The site contains the largest collection of Pictish inscribed symbols in one place, which are probably some of the first ever made. Other carvings include early Christian crosses and a boat over 1,000 years old.

With the ruins of the medieval Macduff Castle and remains of later industrial activity, there is archaeological evidence for activity on the site for the last 4,000 years.
