No 6: Westminster Abbey
Westminster Abbey has been the location of crowning every Monarch since the 11th century. Since 1550, however, the building has a new status: Church of England.
It has become the premier location for Royal Weddings – including Will and Kate’s in 2011 – having had 16 wedding ceremonies over the years.
Currently open to the general public; the guided tours are highly recommended. You may even get to go in restricted areas, opposed to the self guided tour.
