The biggest tourist attraction in the UK is arguably the Tower of London. Located in central London on the north bank of the River Thames, this castle was originally built by William the Conqueror in the 11th century.
The Tower of London features impressive medieval architecture, fun tours from the Tower’s Beefeaters, and various exhibits, including the monarchy’s Crown Jewels. It all combines to make a UNESCO Heritage Site that is a true symbol of the UK’s rich history and culture.
