grated cage in the prison gateway, where certain prisoners were allowed to beg for alms and speak with passers by. Capital punishment was normally the gallows, plus the stake at Wincheap for religious martyrs in the time of Queen Mary. 19th–21st centuries In the 19th century, the city walls that joined the gateway to the back of the drum towers were removed. Following this, in 1823–1829, a jailer's house was built on the north side, and this became the headquarters of Canterbury City Police. It is now a bar and cafe, whose dining room is still known as "The Parade Room", with a police truncheon used as its badge. The disused iron bridge which connects the Westgate with the bar and cafe dates from this time. Contemporary with this work was the building of St Peter's Place on the south side of the Westgate, along with passages around the Westgate and a new road across the Stour, to cope with increased traffic. At the end of the 19th century the Westgate was used as a temporary repository for the city archives, and a museum was opened in the gatehouse in 1906. In 2009–10, Canterbury City Council considered closing the museum, now called the Westgate Towers Museum, which proved to be a controversial option. An additional year's funding was made available to give time to examine alternative operating models, and in 2011 the museum was reopened by Charles Lambie, the chairman of the trustees of Canterbury Archaeological Trust, who intended to build an extension to the building focusing on the penal history of Westgate. Lambie died in 2012, having invested £1 million in the project, causing the closure of the museum and generating fresh questions about the building's future. In 2014, the council agreed to assign the lease to the One Pound Lane company, who stated that they intended to reopen the existing museum and develop a restaurant and bar in the premises. The Westgate reopened to the public on 3 August 2015. In the 21st century, Westgate is the largest surviving city gate in England. The gateway is protected under UK law as a Grade I listed building, and a trial to ban road traffic from passing through the gate was undertaken in 2012. Architecture The gatehouse is expensively faced in coursed ashlar of Kentish ragstone. It has battered plinths to the drum towers, battlements, machicolations and eighteen gunloops: a
