The Old Henllys site contains earthworks of a rectangular enclosure, 24m by 20m, defined by a bank and ditch, having a possible longhouse platform, 14.3m by 9.0m, within its north-east angle.

This site has been classified as a moat and as a deserted medieval village, however a more recent interpretation views it as house and croft. A chapel recorded in this vicinity may be connected to this site (Nprn11802).
