The Palace of Westminster – aka the Houses of Parliament – are one of the most iconic buildings in the world. Since it’s a ‘working’ building and government is going on there, it’s pretty difficult to have a look around.

They now offer tours every Saturday, even when Parliament is in session and you get a chance to see the insides of the Palace. You must book ahead, you can’t just show up on the day. Tours of Elizabeth Tower (which houses Big Ben) are not available for overseas citizens.
