The Tower of London is England’s most formidable royal fortress, standing guard on the banks of the great River Thames. It is home to a thousand years of bloody history and is one of Britain's most iconic landmarks. At almost every chapter in London's history, ‘the Tower’ has had a starring role. Built by William the Conquer as part of the Norman Conquest of England in the 11th century, it was designed to dominate London's skyline. The ancient fortifications are set in grounds the same size as those of the White House, but this is far more than just a castle, protecting London from her enemies.
