We’re usually a little wary when it comes to gigantic observation wheels, but there breadth and scope of the London Eye really sets it apart from the rest. The views are deserving of the breathtaking sobriquet, while no expense is spared when it comes to dispensing a wealth of information in a wide variety of languages. Open to the public since the year 2000, this is the most popular paid tourist attraction in the entire country, attracting almost four million wide-eyed visitors annually. Standard tickets start at £27.
