St Paul’s Cathedral was built between 1675 and 1711 by Sir Christopher Wren. The foundation stone was laid in 1675 when Wren was 43 years old, and the last stone was put in lace by his son 35 years later. It was the fifth cathedral on the site. The previous Norman one was even larger than Wren’s building and had the tallest ever spire. It was destroyed in the Great Fire of London of 1666.
