Chester Castle: Agricola Tower and Castle Walls

The 12th-century Agricola Tower was the first stone gateway to Chester Castle, which had been founded by William the Conqueror in 1070 in the south-west part of the city. On the first floor is the chapel of St Mary de Castro, which contains some exceptionally fine wall paintings from about 1240. By climbing the nearby stairs to the wall-walk, you can appreciate the castle's position within the city.
