Parliament (Palace of Westminster) is where all the politicians hang out to debate current issues and legislation. The building itself has a beautiful gothic-style look.
The oldest part of Parliament houses was originally built in 1097 on the site of William the Conqueror's first palace.
Red lines on the floor of the chamber of the House of Commons, one ahead of each side of the front bench, are supposedly greater than two sword lengths apart so that no opposing members become embroiled in a duel mid-debate.
Visitors are welcome to watch debates in both Houses from the public galleries. Watching debates in Parliament is free of charge and tickets are not required for general debates. On most days you can just turn up and wait for entry to either Chamber on the day. However, the gallery can get full quickly. Visitors wishing to watch debates should enter via the Cromwell Green entrance.
You can also book a guided tour of Parliament from the inside, which can be followed by some afternoon tea.

Please note that Big Ben is right next to Parliament, however it is going through repairs and therefore you wont be able to see it.
