Checked in at one of the world's five great palaces: Buckingham Palace

Buckingham Palace is a royal palace in the United Kingdom, located within the city of Westminster, and is a four-story square courtyard building. It serves as the Queen's office location and her residence in London, as well as the administrative headquarters of the royal family. It is one of the world's five great palaces, alongside the Forbidden City, the White House, the Palace of Versailles, and the Kremlin, and it is also one of the few royal palaces still in use today. The palace is a four-story cubic gray building with a solemn main entrance that hangs the royal coat of arms, symbolizing the center of British royal power. The square in front of the palace features numerous statues and the Victoria Memorial, expanded by Edward VII, with a golden statue of Victory standing atop a tall marble pedestal, gleaming in the sunlight. Inside, there are over six hundred rooms including a ceremonial hall, music room, banquet hall, and galleries. The vast royal garden is filled with blooming flowers, offering a breathtaking view. The parts of Buckingham Palace open to the public include the throne room, music room, and state dining room, which are often in high demand, so it's best to book in advance. Every morning, the famous Changing of the Guard ceremony takes place at Buckingham Palace, becoming a major spectacle of British royal culture. From April to September, the Royal Guard at Buckingham Palace performs the changing ceremony from 11:30 to 12:00, and during other months, it takes place every two days at 11:30.
