You'll find this rather lovely building in Westgate Gardens, near Westgate Towers (one of the city's ancient gates).
The house has been built around one of the 21 bastions of Canterbury's Medieval city wall. although little remains of the wall in this part of the city (you'll need to go to the east to see it) this bastion, and Westgate Towers, somehow survived.
There is map evidence of buildings on the site since at least the 1400s but the existing house was built during Victorian times (apart from the bastion element, of course), probably around 1850. There were once two further wings to the house, but they were demolished in the 1870s.
The 11-acre gardens were given to the city for public use in 1936, and the house itself now acts both as the Mayor's office and as civic function rooms.
Worth a look....
The Mayoralty Tower House is nestled in the middle of the beautifully landscaped Westgate Garden. This most fascinating ancient stone building house is now the home of the Lord Mayor. The house features a wide range of contrasting, but surprisingly complimentary architectural styles. The wing on the left resembles the rook of a Gothic fortress, while the five lobed Baroque facade over the center section gives the building exterior a most interesting look. The narrow arched windows were added much later in the Victorian era. The sculpted flower and shrub gardens frame this fine old house in a very picteresque manner.
more later !
This lovely building is set in the gardens next to Westgate and was donated to the town by Stephen and Catherine Williamson as a token of 150 years of family association with the town and 50 years' residence in the house . . . lucky people.
This building is located in Westgate Gardens, it is a Victorian Building now used as the Lord Mayors House.
