Explanation:

[STC002702] The London Eye has our attention. The Eye, which was constructed in 1999 as part of the festivities commemorating the century, is now known as one of the largest Ferris wheels in the world. The London Eye, which is also known as the “Millennium Wheel,” is located on the South Bank of the River Thames. It is 443 feet tall. It kept the ‘tallest’ title for six years, until its record was broken by the Star of Nanchang in China. However, the Eye has become an instantly recognizable representation of London, and it currently receives over 3.5 million visits annually. That’s some serious insight right there.
