Since King Charles I assumed the throne in the early 17th century, the Royal Family has amassed a vast and priceless collection of artwork, sculpture, ceramics, furniture, and jewellery. This gallery features a rotating selection of around 400 pieces from the palace's treasures, with an audio guide (included in the ticket price) to lead you around in about an hour. Unless you have a keen interest in the temporary exhibition, however, other galleries in London may provide a more rewarding experience, as they are free.
