Your tour starts from Westminster Abbey, perhaps the most beautiful early Gothic building in Great Britain and still used for daily worship and royal functions. The Abbey, a royal mausoleum for many centuries, was used from 1066 after the coronation of William I to crown all kings and queens of England, except two. Rebuilt in 1220 in the then new Gothic style, inside is the Henry VII Chapel (1503-19), this is one of the most beautiful examples of the perpendicular Gothic.
