An outer, lower and upper bailey can be made out and there was also a cistern.
The site covers an area of 51 x 33 metres, the tower has a diameter at its base of about 9 metres and a wall thickness of 3 metres.
The only easily accessible, western, side of the castle was also protected by a ditch.
The inner and outer shell is made of horizontal layers of brick, whilst the core is lined with cut stone laid in a herringbone pattern (opus spicatum).
