Contabilidad

London's buildings are too diverse to be characterized by any particular architectural style, partly due to their varying ages. Many grand houses and public buildings, such as the National Gallery,are constructed from Portland stone. Some areas of the city, particularly those just west of the centre, are characterized by white stucco or whitewashed buildings. Few structures in central Londonpre-date the Great Fire of 1666, these being a few trace Roman remains, the Tower of London and a few scattered Tudor survivors in the City. Further out is, for example, the Tudor period Hampton CourtPalace, England's oldest surviving Tudor palace, built by Cardinal Thomas Wolsey c. 1515. Wren's late 17th century churches and the financial institutions of the 18th and 19th centuries such as theRoyal Exchange and the Bank of England, to the early 20th century Old Bailey and the 1960s Barbican Estate form part of the varied architectural heritage.
