Thursdays at 2:30 p.m. | St. Paul's Tube | The dome of St. Paul's seemed to ride the sea of fire like a great ship. Ludgate Hill was carpeted in hosepipes. Two hundred people died that night. On the north side of the cathedral 63 acres became a waste of smoking ash and rubble. Another 100 acres were completely devastated in other raids that autumn. At the finish, out of the City's tight-packed 461 acres, 164 were reduced to ruin. And this was just 1940. Learn more about London Walks.
