Tower of London

The massive White Tower is a typical example of Norman military architecture, whose influence was felt throughout the kingdom. It was built on the Thames by William the Conqueror to protect London and assert his power. The Tower of London – an imposing fortress with many layers of history, which has become one of the symbols of royalty – was built around the White Tower.

Canterbury

Canterbury, in Kent, has been the seat of the spiritual head of the Church of England for nearly five centuries. Canterbury's other important monuments are the modest Church of St Martin, the oldest church in England; the ruins of the Abbey of St Augustine, a reminder of the saint's evangelizing role in the Heptarchy from 597; and Christ Church Cathedral, a breathtaking mixture of Romanesque and Perpendicular Gothic, where Archbishop Thomas Becket was murdered in 1170.
