Knaresborough Castle

This is where you flee if you've just assassinated Archbishop Thomas Becket. The castle was built by the Normans circa 1100, but its royal heyday was 1200-1400. In 1648 it was "slighted" by the Parliamentarians, partly demolished to prevent rebels using it in future, as were many others across Britain and Ireland. The citizens promptly looted the ruins (an early form of recycling) to build their own mansions with "castle stone". The Courthouse Museum within is an original Tudor courthouse.
