Winchester Cathedral in Hampshire has a long royal history peppered with kingly coronations and regal burials. It has also been the setting for two very royal weddings. Prince Harry's ancestor, King Henry IV of England, married his second wife, Joanna of Navarre, here in 1403 at the start of a seriously loved-up union. Less happy was the marriage between Mary I, the first woman to rule England as queen in her own right, and King Philip II of Spain. Their wedding, in 1554, led to four years of misery, but don't let that put you off.
As well as the cathedral, you can visit the Great Hall, which has hosted royal guests including Henry VIII and which contains a replica of King Arthur's Round Table.
