The roofless shell of a medieval church on the High Street, kept as a memorial to merchant seamen lost at sea and to the crew of the Titanic. The original twelfth-century church served the parish of merchants and ship workers around the medieval port. On 30 November 1940 it was burned out by German incendiaries; the walls and arcades survived, and the city decided to preserve the ruin rather than rebuild.
Inside, plaques line the walls honouring local crew members lost on the Titanic, the Empress of Britain, and dozens of other Allied merchant ships. The ruin is open during daylight hours and free. It is one of the most affecting small spaces in the city.
