Shrewsbury castle is a well preserved castle which dates from fortifications in the town first built by Roger de Montgomery in 1070 which included extensive town walls as well as the castle. Being on the border area between England and Wales the castle saw it's share of conflict, being held for a time by Llywelyn the Great, Prince of Wales in 1215.
The castle was rebuilt during the English Civil War and also restored by Thomas Telford in 1780. Not much of the original castle now survives though the current castle is a fine building made from red sandstone which is the home of the Shropshire Regiment museum.
