The lantern and fittings cost £250 7s 6d, including the adaptation of an 'earlier tower'.

These would have belonged to an early tower of the castle.

The current building dates from the Restoration period, built around and incorporating an earlier fortified tower.

It was built around 1545, but an earlier tower may have been either planned or actually built.

The upper part of this early 18th-century tower was demolished in 1830.

An earlier wooden tower was erected at the site on June 3, 1879.

There had probably been an earlier tower, because the present one contains remains of Norman work.
