William the Conqueror chose the site for the castle in the 11th century as it was on high ground and just day’s journey from his base in the Tower of London. Successive monarchs have made alterations that render it remarkable monument to royalty’s changing tastes. George V’s affection for it was shown when he chose Windsor for his family surname in 1917.

The Round Tower in Windsor Castle was first built by William the Conqueror, in 1170 it was rebuilt in stone by Henry II. It now houses the Royal Archives and Photographic Collection. The ceremonial route show the main State Apartments that are used today by The Queen and members of the Royal Family. Within these rooms The Queen hosts official visits by Heads of State from other countries, investitures, and awards ceremonies, where British men and women are recognised for their achievements.

The architectural highlight of the Windsor Castle is St Chapel, it is one of England’s outstanding  Perpendicular Gothic churches, ten monarchs are buried here.

Dwarfed by the enormous castle on the hill above-in fact its original purpose was to serve the castle’s needs – the town of Windsor is full of quaint Georgian shops, houses and inns. The most prominent building is the Guildhall, where Prince Charles and Camilla Parker – Bowles were married in 2005. Eton College, one of the most prestigious schools in Britain, lies just a short walk away. Windsor Great Park stretches from the castle 5 km (3 miles) to Snow Hill. To the southeast is the meadow of Runnymede, where King John was forced to sign the Magna Carta.
