many fine terraces and villas facing the road, and at right angles to it. In the early 19th century, the romantic medieval gothic style appeared, partially as a reaction against the symmetry of Palladianism, and can be seen in buildings such as the Bristol City Museum and Art Gallery, the Royal West of England Academy, and The Victoria Rooms. Riots broke out in 1793 and 1831; the first over the renewal of tolls on Bristol Bridge, and the second against the rejection of the second Reform Bill by the House of Lords. The population by 1841 had reached 140,158. The Diocese of Bristol had undergone several boundary changes by 1897 when it was "reconstituted" into the configuration which has lasted into the 21st century. 20th century From a population of about 330,000 in 1901, Bristol grew steadily during the 20th century, peaking at 428,089 in 1971. Its Avonmouth docklands were enlarged during the early 1900s by the Royal Edward Dock. Another new dock, the Royal Portbury Dock, opened across the river from Avonmouth during the 1970s. As air travel grew in the first half of the century, aircraft manufacturers built factories. The unsuccessful Bristol International Exhibition was held on Ashton Meadows in the Bower Ashton area in 1914. After the premature closure of the exhibition the site was used, until 1919, as barracks for the Gloucestershire Regiment during World War I. Bristol was heavily damaged by Luftwaffe raids during World War II; about 1,300 people living or working in the city were killed and nearly 100,000 buildings were damaged, at least 3,000 beyond repair. The original central shopping area, near the bridge and castle, is now a park containing two bombed churches and fragments of the castle. A third bomb-damaged church nearby, St Nicholas was restored and after a period as a museum has now re-opened as a church. It houses a 1756 William Hogarth triptych painted for the high altar of St Mary Redcliffe. The church also has statues of King Edward I (moved from Arno's Court Triumphal Arch) and King Edward III (taken from Lawfords' Gate in the city walls when they were demolished about 1760), and 13th-century statues of Robert, 1st Earl of Gloucester (builder of Bristol Castle) and Geoffrey de Montbray (who built the city's walls) from Bristol's Newgate.
