Office (1829), the Bank of England, the Mansion House and the National Gallery. The Tower Bridge is clad in Portland stone (as well as Cornish granite). Portland stone was used in 1923 to build the supporting pillar of the Grace Gates at Lord's Cricket Ground. Recently, Portland stone has been used in the building of Chelsea Barracks, Wilkins Terrace at UCL University College London, St James's Market Haymarket, London and Green Park tube station. Portland stone is prevalent in Manchester despite the historical preferred use of hard-wearing materials, such as Burmantofts and sandstone to resist the harsh industrial environment. Portland stone was mostly used in Manchester during the 1930s. Manchester buildings with Portland stone exterior include 100 King Street (1935), Arkwright House (1937), St. James Buildings (1912), Manchester Central Library (1934), Kendal Milne (1939) and Sunlight House (1932). Two of Liverpool's Three Graces, the Cunard Building and the Port of Liverpool Building, are clad in Portland stone which surrounds their reinforced concrete frames. The Nottingham Council House, completed in 1929, is also built with Portland stone, as are the public buildings in Cardiff's civic centre. Architect Charles Holden significantly used the stone in his major commissions of the 1920s and 1930s, including Senate House and 55 Broadway, the home of the London Underground. The 1929 steel framed building (one of the first erected in the United Kingdom) of the London School of Hygiene & Tropical Medicine, based in Keppel Street, has a Portland stone façade to complete its stripped Classical design. After the Second World War (1939–1945), the bombed out centres of many English towns and cities, such as Plymouth, Bristol, Coventry and London were reconstructed using vast facades of Portland stone. Many of the buildings surrounding the flagship Parkinson Building at the University of Leeds are clad in Portland stone, including the Michael Sadler Building, the Chemistry and Engineering buildings and the new Laidlaw Library. Oxford typically uses oolitic limestone in its buildings, and the Ashmolean Museum has been refurbished using a large amount of Portland stone. Portland stone has also been used across the world. Examples include the UN building in New York, the Casino Kursaal in Belgium and the Auckland War Memorial Museum. Most of the important civic and administrative buildings which survive from 18th and 19th century Dublin, Ireland, known then as "the second city of the Empire", are of Portland stone, including City Hall (1779),
