Dunbeg Fort, Dingle Peninsula, Kerry, Ireland. — Jim Linwood

The location of An Dún Beag, or Dunbeag Promontory Fort, makes it one of the most dramatic archaeological sites on the peninsula. It has been excavated and results show that it was begun in the late Bronze Age, 800 BC, and was used right through the Celtic period up to the 10th century. Even the excavation results did not reveal conclusively what the site was used for; it may have been defensive, or used for ritual purposes, or it may simply have just been lived in. This small but impressive fort is located on a sheer cliff promontory which projects South into Dingle Bay at the base of Mt. Eagle.
