[1] Built as part of Chester's defensive system, it was used in the 19th and early 20th centuries as a museum.

[2] Around this time a statue of Queen Anne which had formerly been in the Exchange before it burned down was installed on the steps of the tower.

The tower closed as a museum in 1901–02 while the city walls were rebuilt, and re-opened in 1903, attracting 12,000 visitors that season.

On the opposite side another doorway leads on to the spur wall to the Water Tower.

[1] Inside the tower is a fireplace and a closed staircase which is lit by a single slit window.
