Originally built c1440 but only the square tower survived until the early 19th century, when it was demolished. The present structure was built in c1577, and was originally a great palace house similar to Huntly Castle, but of which only the hall block and staircase tower now survive. A baronial house was added in 1815 but this was demolished in 1960 and the castle has been restored to the 16th century structure as near as possible. Masons known are John Kemlock and William of Ennerkype (1440). 

48 marks were recorded by H G Slade, of at least 10 or 12 different masons, but further survey is still being undertaken by the Project as more marks are known to exist. On Cellar door 3 there is one stone with 3 different marks, each on a different angle so possibly a re-used stone. A number of the stones may well be re-used from the earlier tower. In the Pit off Cellar 1 there are 2 marks ,No's 12 and 13, which are distinctly different from all others, being much larger. These may belong to a Victorian re-build in this area. Excavations in 2017 by Colin Shepherd on the site of the earlier castle uncovered some very fine dressed masonry, on which 4 masons marks were recorded on 4 blocks. It is thought that the footings belong to a castle dating to 14th-15th century.
