Small and complex coastal promontory fort located on prominent W-facing, rocky promontory immediately N of Abereiddi Bay on N coast. Promontory 270m long jutting out into Irish Sea. Sea cliffs to N, S and W, landward to coastal plateau on E. Multivallate, and eroded on S, defences cut off the promontory c. 140m from tip to give enclosed area c. 110m by 60m, with area estimated at c. 0.66ha. Defences difficult to determine and have been investigated by DAT. They consist of four or five banks and ditch. Outer bank on E most massive, with no outer ditch, but to c. 4m wide and over 3m above a rock-cut ditch on its inner W side. Second bank to W consists of unexcavated bedrock between two ditches, rather than built bank. Two more sets of slight bank and ditch to W then gap of 20m. Here promontory widens out and protected by a further bank running along a natural rise. Entrance possibly on S side, where all banks stop short of sea cliff. N slope steep and here quarrying, but to W several slight platforms cut into slope may be hut sites. Post medieval Abereiddi Tower to W at highest point of promontory. Ditch running N-S c. 140m E of defences modern quarrying and further to E massive modern quarrying isolates whole of rpomontory from mainland. Site under rich coastal grassland with bare rock exposed. On 1st Ed. OS map (1889). Minimal investigations, undated.
