A further bailey to the north was noted in 1931 but this has subsequently disappeared. On top of the motte there are two fragments of a shell keep wall about 5m high.
The castle is thought to have been built circa 1090. Although already ruinous it was used in the Civil War and was subsequently slighted to prevent re-use.
The stonework and mound were stabilised in 2013. The archaeological report was printed in the Woolhope Club, Transactions, 2013, pp. 112-115.
