On my way to Dorset I popped into three castles on the way to exploit my English Heritage membership
First was Old Wardour castle, which has a compact hexagonal design
As is almost always the case it's been knocked about during the civil war
But unusually it was done by the Royalists, by accident!
Then onto Sherborne Old Castle, which had an octagonal design. An impressive entrance gate
But very little left of the keep/bishops residence.
It had an unusual water gate as virtually the whole castle was surrounded by a lake.
But only the stairs remain.
Then onto Maiden Castle for a bracing walk, but I left my camera in the car!
