The 13th-century Chapter House was described by the medieval historian Matthew Paris as 'incomparable'. Sir Giles Gilbert Scott, the architect behind the last major work carried out there, in the 1870s, called it 'a structure perfect in itself'

The worn but fascinating medieval wall paintings are among the highlights of the Chapter House. The angels depicted in the heads of the arches remain largely visible

The Chapter House boasts what is widely regarded as the most extraordinary tiled medieval floor in Britain. It was hidden beneath timber until Sir Giles Gilbert Scott's late 19th-century renovations once more brought it to light

Each of Westminster Abbey's four cloisters is about 100ft long. Constructed largely between the 13th and 15th centuries, they were rebuilt after the great fire of 1298
