A 'promontory fort' is a
defensive structure located above a steep cliff, often only connected to the mainland by a small neck of land, thus utilizing the topography to reduce the ramparts needed. Although their dating is problematic, most seem to date to the
Iron Age. They are mainly found in
Ireland, the
Isle of Man and
Cornwall.
Ireland
Only a few Irish promontory forts have been
excavated and most seem to date to the
Iron Age, though some, like Dunbeg (Co. Kerry) might have originated in the
Bronze Age. Others, like
Dalkey Island (Co. Dublin) contain imported Eastern Mediterranean pottery and have been reoccupied and changed in the early
medieval period. Dunbeg contains an early medieval
corbelled stone hut (
clochan).
Isle of Man
On the Isle of Man promontory forts are found particularly on the rocky slate headlands of the south. Four out of more than 20 have been excavated and several, especially in
Santon, can be visited using the
Raad Ny Foillan coastal footpath. All have a
rampart on their vulnerable landward side, and excavations at
Cronk ny Merriu have shown that access to the fort was via a strongly-built gate.
The
Scandinavians who arrived in Mann in the eighth and ninth centuries sometimes re-used these Iron Age promontory forts, often obliterating the old domestic quarters with their characteristic rectangular houses; the fine example at Cronk ny Merriu has been used as the basis of the reconstruction in the
House of Manannan museum in
Peel.
Cornwall
Promontory forts can be found all along the coast of
Penwith. Maen Castle, near to
Land's End is one of the oldest, having been dated to around 500BC. Another is to be found at
Dodman Point.
