Among the attractions of this park on the outskirts of town is its crenelated tower, an 18th-century "folly" built by the sixth earl of Coventry and later used by William Morris as a retreat. The panoramic view from the top takes in three counties and looks over peaceful countryside and wandering deer. There are plenty of nature trails and good spots for picnics, as well as a café. Wall panels on the three floors inside describe the tower's connection with the local Arts and Crafts movement and World War II. Note that the spiral staircase is narrow and steep. A nuclear bunker is open on weekends during the summer.
