The London Eye is this iconic giant Ferris wheel located on the South Bank of the River Thames. Standing at about 135 meters tall, it offers some seriously stunning views of the city. People hop on for a slow ride that lasts around 30 minutes, giving them plenty of time to snap photos and take in landmarks like Big Ben and Buckingham Palace from above. It’s especially magical at sunset when the city lights start to twinkle. Built in 1999, it quickly became one of London's must-see attractions, drawing in millions of visitors each year who want to experience the skyline from a whole new perspective. Plus, it's got a pretty cool design, with glass capsules that let you see everything clearly as you ascend.
