The Stockholm Royal Palace is located on the island of Stadt in the Old Town. It is the place where the King of Sweden works and celebrates, and is also a major tourist attraction in Stockholm. The palace was built in the Middle Ages. In the early days, it was a military fort. It was gradually transformed and expanded at the end of the 17th century and became the royal palace of today. The palace is built on the water, and the building is square. It is a small square castle with a white exterior and elegant atmosphere. Now the Swedish royal family does not live here, but lives in Queens Island in the suburbs, but the king drives to the palace every day to go to work.
