#1 St Paul's Cathedral (London)
St Paul's Cathedral in London serves as the seat of the Anglican Diocese. Rebuilt by Sir Christopher Wren after the Great Fire of 1666, it blends neoclassical and baroque styles. Its massive dome draws inspiration from St. Peter's Basilica and the Hôtel des Invalides. Famous for its 125 bells and Golden Gallery, the cathedral hosted the funeral of Churchill and the wedding of Charles and Diana. The crypt holds notable British figures, including the architect Wren himself.
