In Parliament Square before going on a guided tour inside.
We visited the British Museum including the Sutton Hoo treasure, Roman items found in Suffolk, the Pathenon Statues from Greece and lots of amazing Egyptian artefacts.
We walked around Westminster seeing the Horseguards, Downing Street, Westminster Abbey and statues of famous politicians.
Inside Parliament photos are only allowed in a few areas such as St Stephen's Hall and Westminster Hall - the original Parliament rooms.
This year we had a special thrill on our tour. We visited the Queen's rooms and spent time in the House of Commons Public Gallery watching a live debate.
We also met and spoke to Lord Phillips - a member of the House of Lords.
On the way home London looked fantastic with all the lights coming on. We drove over Tower Bridge and past the Tower of London.
