Buckingham Palace is the Queen's home and her "office".
At half past eleven most mornings, the soldiers change the guard at Buckingham Palace. It takes about thirty minutes, and you can stand in front of the palace and watch. Hundreds of visitors do this every day.
The Tower of London is the City's oldest building. It stands by Tower Bridge, and next to the River Thames.
In the past, it was a palace and a prison. Kings (and sometimes queens) put their most important prisoners there, and many of these prisoners never came out alive.
You can see the Crown Jewels in the Jewel House, and visit the Bloody Tower.
There are thirty-six Yeoman Warders, or Beefeaters, at the Tower.

Hyde Park first opened to the people of London in the seventeenth century.
You can walk or sit under the trees. In the centre is a lake called Serpentine, and you can take a boat out on the water.
