It's a place to visit for its incredible antiques and its history. The Abbey is where british royalties get married.
WESTMINSTER ABBEY. The place for royal coronation. William the Conqueror was the first to be crowned here in 1066 and every monarch since him except Edward V and Edward VIII was crowned in the Abbey.
This is the place where many of Britain's great personalities are buried (including Sir Winston Churchill - the greatest politician of all times in my opinion). Note that it is a World Heritage site.
