Another great Thames-side attraction, Hampton Court is one of Europe's most famous palaces. Its Great Hall dates from Henry VIII's time (two of his six wives supposedly haunt the palace), and it's where Elizabeth I learned of the defeat of the Spanish Armada.
Other interesting features include the Clock Court with its fascinating astronomical clock dating from 1540, the State Apartments with their Haunted Gallery, the Chapel, the King's Apartments, and the Tudor tennis court.
The gardens are also worth visiting - especially in mid-May when in full bloom - and include the Privy Garden, the Pond Garden, the Elizabethan Knot Garden, the Broad Walk, an area known as the Wilderness, and of course, the palace's famous Maze.
