 The Parliamentarians left it much as it is today, the stone from the castle being taken and used to repair the town's damaged buildings.Parts of the great tower still remain, but because of the damage caused during the Civil War, it now leans at an angle of 15 degrees, 4 times the lean of the leaning tower of Pisa.The castle grounds were excavated over three days by archaeological television programme "Time Team", clarifying the layout of the castle and the history of its construction.
