Dunnicaer

Dunnicaer, or Dun-na-caer, is a precipitous sea stack just off the coast of Aberdeenshire, Scotland, between Dunnottar Castle and Stonehaven. Despite the unusual difficulty of access, in 1832 Pictish symbol stones were found on the summit and 21st-century archaeology has discovered evidence of a Pictish hill fort which may have incorporated the stones in its structure. The stones may have been incised in the third or fourth centuries AD but this goes against the general archaeological view that the simplest and earliest (Class I) symbol stones date from the fifth or even seventh century AD.
