          At  the  highest point of the town stands the remains of a 13th century windmill.  It is a stone tower known locally as the “Billy Wynt”.  The tower was already shown on a map of South Wales  in 1729 as a  windmill next to the town and was said to have been destroyed during a battle in the Middle Ages.  By the early 19th  century  the  tower was in ruins  and  in 1893 it was restored as an attraction for the town of Llantrisant.
