Project area 8 contains the two intriguing and mysterious coastal prehistoric sites of Castell Bach and Cardigan Island. Both are situated along the beautiful south Ceredigion coast and represent some of the best prehistoric archaeological remains in the region. Whilst they are clearly significant to the story of the prehistoric period in this part of Wales very little is known about them due to them being severely under researched.
The site of Castell Bach is located on a secluded and well-hidden stretch of coastline around 3km southwest of Newquay, Ceredigion. The coastal fort is situated within an amphitheatre-like ‘coastal bowl’ where it is centred upon a small, almost pyramid-like, islet. Its defences comprise a circuit of two concentric banks and ditches which enclose a small promontory. Evidence of an entranceway survives on its eastern side. It is possible that the promontory previously enclosed the entrance to a land bridge that may have connected the small central islet to the mainland. To the east of the fort are also the remains of a third bank and ditch which create an annex, possibly added later as an extension to the inner fort. The inner defences are now actively eroding on their western side.
