Situated on the banks of the River Thames, Big Ben and the Houses of Parliament collectively form one of the most iconic and recognizable landmarks in London. Big Ben refers specifically to the massive clock tower, officially known as the Elizabeth Tower, which stands tall over the Palace of Westminster, home to the UK Parliament. Completed in 1859, the neo-Gothic architecture and intricate detailing of the tower and the adjacent parliament buildings reflect the historical and political significance of this site. The clock, with its resounding chimes, has become synonymous with London itself, drawing millions of visitors each year.
