Palace of Westminster

The Palace of Westminster earns its spot on our list as one of the most iconic and historically significant landmarks in London. Sitting gracefully along the River Thames, this architectural masterpiece is the heart of British politics and home to the UK’s Parliament. Visitors can admire the stunning Gothic Revival design from the outside or take a guided tour to explore the grandeur of the House of Commons and House of Lords. The highlight, of course, is Big Ben—the world-famous clock tower that’s part of the complex. Whether you’re soaking in the view from Westminster Bridge or diving into centuries of political history on a tour, this is a must-see that blends history, power, and incredible architecture all in one.
