Tower of London Home to the Crown Jewels, the Tower of London reverberates with dark secrets, where priceless jewels glint in fortified vaults and pampered ravens strut the grounds. Founded by William the Conqueror in 1066, and enlarged and modified by successive sovereigns, the Tower of London is one of the world's most famous and spectacular fortresses. Discover its 900-year history as royal palace and fortress, prison and place of execution, mint, arsenal, menagerie and jewel house. Thames River Sightseeing Cruise The best way to see the sights and splendor of this great capital city is from the deck of a boat. The River Thames weaves its way through London, with history around every bend. You'll experience the sights and splendor of this great city from the comfort of a modern, all-weather, wheelchair-friendly RiverLiner, with open upper decks and spacious lower saloons with panoramic windows. Take advantage of two bars providing light refreshments, snacks and alcoholic beverages. Cruises depart frequently from Westminster Pier, Waterloo (London Eye) Pier, Tower and Greenwich Pier. The shortest trips between piers last around 30 minutes, while the full round trip takes 2.5 leisurely hours.
