St Olaf's Church

St Olaf's one of only a handful of medieval City churches that escaped the Great Fire of London in 1666.
Charles Dickens was also very fond of the church. He nicknamed it the 'Churchyard of Saint Ghastly Grim'.
He tells a wonderful tale about being an insomniac and at midnight, in the middle of a thunderstorm, decided to take a hackney carriage to look at the place. The gateway has skulls pierced by metal and he wanted to see them in lightening, he found the skulls most effective, having the air of a public execution, and seeming, as the lightning flashed, to wink and grin with the pain of the spikes.
