The English seaside city of Brighton is home to the world’s thinnest observation tower, a structure only 3.9 meters in diameter, with a height-to-width ratio of over 40:1.
Conceived and designed by Marks Barfield Architects, the same firm behind the famous London Eye wheel, the i360 coastal observation tower in Brighton, UK looks like a giant needle pointing at the sky. It’s not the only observational tower in the world, but it is the thinnest one ever made. It has a diameter of only 3.9 meters, or 12.8 feet, at its widest point, and stands 162 meters tall. Although it is often described simply as a vertical cable car because of the technology it uses to drive a tourist-filled pod up and down, the i360 is actually an engineering marvel.
