Bristol castle built once by decree of William the Conqueror, for centuries defended the city. For the first time in written sources mention the castle in 1088. Then it was a wooden fortress, but soon the castle was rebuilt in stone. The high walls and towers, the most advanced at that time to strengthen, good location between the two rivers made it impregnable. This stronghold has played a significant role in the war for the throne of England after the death of Henry I. It contained the noble captives and hostages.

However, already in the middle of the XVI century, the castle begins to break down, but the city authorities could not do anything with the castle is owned by the king, and the castle became a refuge for lawbreakers. In 1656 on the orders of Oliver Cromwell, the castle was demolished.

Now, the castle is a park, which is called Castle Park. Somewhere in the park can still be seen the ruins of the castle.
