The building where the UK legislative assembly meets. The present Houses of Parliament in London, designed in Gothic Revival style by the architects Charles Barry and A W Pugin, were built 1840-60, the previous building having burned down 1834. It incorporates portions of the medieval Palace of Westminster. The Commons debating chamber was destroyed by incendiary bombs 1941: the rebuilt chamber (opened 1950) is the work of G G Scott and preserves its former character.
