The London Eye became the largest observation wheel in the world when it opened in 2000. The developers were originally given a 5-year permit, but it was expanded to 24 years in 2003.

Windsor Castle has served as the family home and official residence of the royal family for more than 1,000 years. Queen Elizabeth splits her time between Windsor, Buckingham Palace and her home in Scotland.
If you want to see Windsor Castle, you'll have to head out of the city. The Castle sits about an hour west of London in the county of Berkshire.
At around 1,000 feet high, the Shard is London's tallest habitable building. The tallest British building outside of London is Beetham Tower, which is located in Manchester.

The Collegiate Church of St. Peter may have a humble name, but the gothic structure is one of London's most impressive sites.

Henry VIII used the land as his private hunting ground. It wasn't until 1637 that the land was opened for all to enjoy.

More accurately, it's a bascule bridge, but it does get lifted around 1,000 times a year to let tall ships pass underneath. The iconic structure was built in 1894 to ease the traffic burden on London Bridge, which had been built in 1176 and really was falling down.
The gothic Palace of Westminster is home to Parliament, including both the House of Commons and House of Lords. The current structure was built over medieval remains in the mid 19th century.
The Rosetta Stone has been on display at the British Museum since 1802. Ancient Greek text on the stone helped historians decipher hieroglyphics for the first time, making Egyptian history more accessible.

The 2011 royal wedding took place at Westminster Abbey. It was William's mother and father, Charles and Diana, who famously married at St. Paul's Cathedral in July 1981.

The Duke of Buckingham built the palace to serve as his private residence in 1703. It was converted into a royal palace in 1826 by legendary architect John Nash.
