It’s a huge clock tower next to the Houses of Parliament. The big bell inside is actually called Big Ben, but people often call the whole tower Big Ben! It rings every hour.
This is the official home of the King! It’s a huge palace with hundreds of rooms. You can often see the Beefeaters – guards with tall, furry hats outside.
This historic castle has been a royal palace, a prison, and even a zoo! Today, you can see the Crown Jewels here, and the ‘Beefeaters’, still guard it. And look out for the ravens – legend says if they leave, the Tower will fall!
