Windsor Castle

Windsor Castle, perhaps the most famous castle in England. Window is the oldest and largest occupied castles in the world, so it’s no wonder that it’s a UNESCO World Heritage Site. The castle’s origin date back to Norman times as it was founded by William the Conqueror in the 11th century.

Originally Windsor Castle was a motte-and-bailey castle that formed (along with other castles) a defensive ring around London. To fully protect the city of London it was built in a strategic location near the River Thames.

Though the castle wasn’t built as a Royal residence, it has been the home of 39 monarchs since its construction. St George’s Chapel at Windsor is also the final resting place of Queen Elizabeth IIand many other English Royals.

Warwick Castle

Located on a meander of the River Avon, Warwick Castle is a medieval castle. The first castle was a Norman wooden motte-and-bailey castle but in the 12th century, the castle was rebuilt into a stone castle. The exterior of the castle is a classic example of military architecture. This façade was added during the Hundred Years War.
