A Baroque cathedral built by Christopher Wren between 1675 and 1710 on the site
of the medieval cathedral destroyed in the Great Fire of London in 1666. Its
dome, 111 metres high and modelled on St Peter’s in the Vatican, is really three
shells stacked together: a decorative inner one, a structural cone in the middle
and a light outer skin of lead over timber. It was the tallest building in
London for 250 years, until the BT Tower went up in 1962.
