The Palace of Westminster is the actual name of the Houses of Parliament and can be visited in a 90-minute tour when Parliament is not in session (check the website to see if it’s available on your dates). Saturdays are often a good and available day to visit. The highlight is Westminster Hall which was built by the son of the William the Conqueror over 900 years ago in 1097.
