Wolvesey Castle in the context of Bishop of Winchester

Mary I of England (1516–1558) and Philip of Spain (later Philip II; 1527–1598) married at Winchester Cathedral on Wednesday 25 July 1554.

Henry of Blois (c. 1096 – 8 August 1171), often known as Henry of Winchester, was Abbot of Glastonbury Abbey from 1126, and Bishop of Winchester from 1129 to his death.

He was the son of Stephen II, Count of Blois and Adela of Normandy, a younger brother of Stephen, King of England, and a grandson of William the Conqueror. Henry was also a major patron of the arts, funding the Winchester Bible and the font in Winchester Cathedral. He founded the Hospital of St Cross and built much of Wolvesey Castle.

Winchester city walls are a series of defensive walls in central Winchester, originally built during the Roman settlement of southern Britain, in what was then the settlement of Venta Belgarum. The area surrounding Winchester had been populated throughout the Iron Age, with Britonnic settlements existing at Oram's Arbour, St Catherine's Hill, and Worthy Down; Venta Belgarum took its name from the Belgae tribes of the area. Earthwork defences were constructed around the end of the 2nd century AD, being rebuilt in stone during the latter part of the 3rd century.

Under Saxon rule, Alfred the Great rebuilt Winchester and its defences as part of the burh system developed to protect against Norse incursions. Winchester was later chosen as the location of one of the first Norman castles in England, with Winchester Castle being built alongside the walls in 1067. As well as the royal castle in the West of the city, Wolvesey Castle, the palace of the Bishop of Winchester, was built in the East of the City alongside the River Itchen; during the Civil War known as The Anarchy, the forces of Queen Matilda, on behalf of King Stephen, besieged the forces of Empress Matilda, destroying much of the old city including the urban defences, in an event known as the Rout of Winchester.
