We weren't allowed to take photos inside many of the rooms. When we arrived, we had to put our bags through security, just like at an airport.
Inside, we visited the House of Commons and the House of Lords.
Diana, our guide showed us around.
We stood waiting for Big Ben to chime 12 o'clock.
Westminster Hall, the oldest part of the Palace of Westminster.
Diana told us about what happens at the State Opening of Parliament. We found out that the Queen opens Parliament once a year.
She wears a special crown which travels to the Palace of Westminster in its own carriage!
Lucy pretended to be the Queen, and Josh was Prince Philip.
We then went to a classroom in the Education Centre where we did some activities about the State Opening of Parliament.
Josh pretended to be Black Rod (who we actually saw on our tour!).
Megan dressed up as the Queen.
We had to estimate and then find out how long the Queen's train of her gown is. We then looked at the family tree of the Royal Family.
It was then time for lunch, which we ate in the Education Centre.
Outside the Houses of Parliament.
We walked to see the River Thames and the London Eye at Westminster.
We enjoyed watching the boats and barges on the river. Some of us would like to come back and go on the London Eye.
We then walked up to Downing Street to see where our Prime Minister, Theresa May lives.
Luke even got to wear one of the policemen's hats!
The policemen guarding Downing Street were very friendly and answered lots of our questions.
