In the 12th century many charters refer to 'the vill of the castle of Rachedal'. A charter dated c.1238 gave details of the castle standing on rising ground commanding the valley of the Roche and still known as Castle Hill. The castle was abandoned in the early 13th century. It was documented in 1322.
In 1626 a Gabriel Tayor had a house, known as Castle Hill, on the site, described as being on the 'reputed scite of a castle standing there, but now clean defaced'. Buildings have been erected over the castle bailey and in the 19th century a house was built on the motte.
