Tourists can explore the castle year-round but, since it's a working royal residence, it may be closed at times for special events with little forward notice. The castle's St George's Chapel was the venue for the 2018 wedding of Prince Harry and Meghan Markle, followed by a reception in St George's Hall (pictured).

The final resting place of Queen Elizabeth II can be found at the castle's King George VI Memorial Chapel. Britain's longest-reigning monarch, who was on the throne for 70 years, is buried alongside her parents, sister and husband.
