Not much remains of Castle Newe (pronounced "Neyouw") an altered Z plan tower house of 1604 and mansion from 1831, which had a tall central tower and was designed by Archibald Simpson. The original castle consisted of a main block with rectangular towers at opposite corners. The building was demolished around 1827, and materials used to build an extension of the University of Aberdeen. It was a property of the Forbes family, who made their fortune in India.
