Overview

History & significance

Rhyd yr Onen Mound and Bailey Castle is a motte and bailey fortification located in Wales, designated as a scheduled ancient monument under Cadw reference MG084. The site comprises the characteristic two-part earthwork typical of Norman and early medieval defensive architecture, consisting of a raised mound (motte) with an associated bailey or outer enclosure.
