The tower was probably built by Robert de Lowther, who died in 1383, from Roman stone. It is four storeys high, and has a vaulted basement with an entrance in the north wall. In 15th century a manor house was erected on the north side of the tower and in the 17th century the east side of the tower was built on to.
