This ancient fortress was founded by William the Conqueror and almost 1.000 years of British history have been played out within its walls. It was here that Anne Boleyn was executed. Guy Fawkes interrogated. Richard II and Elizabeth I incarcerated and the 'Princes in the Tower' disappeared without trace. Standing guard by the River Thames, The Tower is an impressive London landmark. Discover the secrets that lie within its walls, marvel at the breathtaking Crown Jewels, stand on the site where three English queens were beheaded and explore the myths and legends that make a visit to The Tower a fantastic day out.

The official residence of Queen Elizabeth II, Buckingham Palace has been opening its doors to visitors since 1993.

Buckingham Palace's most famous spectacle is Changing of the Guard, which begins at 11:30am Apr-July.

The classical dome of St. Paul's dominates the City's square mile. The golden cross surmounting it is 110m (365 ft.) above the ground. In the interior of the dome is the Whispering Gallery, an acoustic marvel in which the faintest whisper can be heard clearly on the opposite side. Sit on one side, have your traveling companions sit on the opposite side, and whisper away. You can climb to the top of the dome for a 360-degree view of London. From the Whispering Gallery a second steep climb leads to the Stone Gallery, opening onto a panoramic view of London. Another 153 steps take you to the Inner Golden Gallery, situated at the top of the inner dome. Here an even more panoramic view of London unfolds.
