A remarkable tumulus known as the Twmpath, near Colwinston, was thoroughly explored under the direction of Mr. F. G. Price, F.S.A., in 1887. The central portion had been excavated several years previously by the then owner of the property, when nine cinerary urns and their contents were brought to light; but as these were not the sort of treasure he looked for, the work was abandoned.
[.. Price] mentions the tradition of a local battle, the slain of which were said to be buried here.
