Substantial wooded inland promontory fort discovered by the Dyfed Archaeological Trust in 2018, following analysis of LiDAR and field investigation, and surveyed in 2019. The fort occupies a narrowing triangular promontory 124m x 129m, with three lines of curving defences enclosing a total area of 0.9 ha. The inner two ramparts are slightly curving and run parallel to one another; the outermost rampart is more irregular in shape and may be a later addition or disturbed at some later date. Recorded during RCAHMW aerial reconnaissance.

Extensive geophysical survey by Tim Young, Cardiff University, in April 2018 of the land to the west of the promontory fort has revealed complex outworks and ring ditches close to the fort. The survey was undertaken in response to the discovery close by of a metal-detected hoard of copper allow artefacts of the latest Iron Age from Jordanston Farm, Llanstadwell, excavated by DAT and National Museum Wales in 2019. Excavations revealed the metalwork originated from the first Iron Age chariot burial discovered in Wales.
