Monument in London
Also known as Big Ben, Elizabeth Tower, Palace of Westminster, Houses of Parliament
Partly free, partly paidSome of it costs nothing, some of it charges.
The Palace of Westminster, Big Ben, and Westminster Abbey form the political and religious heart of London, and the whole group is a UNESCO World Heritage Site. The exterior is free to see from Westminster Bridge and the South Bank, where the Palace, the tower, and the river all line up for the classic photo at no cost. Parliament Square opposite is open public ground with free-to-visit statues of Churchill, Mandela, and others.
Big Ben is really the bell inside the tower, which was renamed Elizabeth Tower in 2012. Most people use the name for the whole thing. The Gothic Revival building seen today was rebuilt after the 1834 fire, which is why such an old institution looks so Victorian.
Paying only starts inside. Westminster Abbey charges for sightseeing entry, but attending a service or Evensong is free and still lets visitors hear the choir under the vaulted nave. The Houses of Parliament offer paid tours, while watching a debate from the public gallery is free when Parliament is sitting, and UK residents can arrange free tours through their own MP.
The budget move is simple: stand on Westminster Bridge, photograph the Parliament facade and Big Ben, walk through Parliament Square, then follow the river past the London Eye toward the South Bank without spending a thing. Buckingham Palace and Trafalgar Square are both a short walk away, so this corner stitches into a full free day in London.
