Saint Paul's Cathedral: According to the city’s history, a Cathedral dedicated to St Paul has overlooked the City of London since 604AD. This religious monument has been a constant reminder to the people of London’s commercial centre of the significance and importance of the spiritual side of life as well as the material side. The present day Cathedral, the fourth to occupy this site, was designed by Sir Christopher Wren, architect to the court and built between 1675 and 1710. Its predecessor was destroyed during the Great Fire of London. The sheer audacity of its architectural and artistic style showcases the determination of five successive monarchs who oversaw its restoration, each committed to ensuring that London’s leading church should be as beautiful and imposing as their own private palaces. Ever since the first service took place here in 1697, Wren's jewel has been where people and events of overwhelming national importance have been celebrated, mourned and commemorated.
