It’s where I fell in love with travel and had my first real experience traveling outside of the United States. The capital city of England is home to a wealth of attractions, including historic landmarks like Big Ben and Buckingham Palace, and world-class museums such as the British Museum and the Tate Modern. In this travel guide, you’ll find the best things to do and see in London.

1. Big Bend

Elizabeth Tower and Big Ben

Big Ben is an iconic symbol of London and is often used to represent the city in films, television shows, and other media.  The clock tower, named Elizabeth Tower, is 315 feet tall (96 meters) and consists of a square base with four clock faces.  Although the name “Big Ben” is generally used to reference the entire tower, it is actually the given nickname for the Great Bell.  The Great Bell, or Big Ben, first chimed in 1859.  It weighs 13.5 tons (13.5 tonnes) and strikes every hour, while the four smaller bells chime every 15 minutes.

UK Parliament offers seasonal 90-minute guided tours of Elizabeth Tower.  Tours lead visitors up a 334-step spiral stairway to the Belfry where Big Ben hangs.  The tour highlights how the clock works and allows visitors to stand next to Big Ben as it strikes the hour.  A good viewpoint to admire or photograph Big Ben is from Westminster Bridge or Parliament Square. 

2. Houses of Parliament
