The list of shipwrecks of Cornwall lists the ships which sank on or near the coasts of mainland Cornwall. The list includes ships that sustained a damaged hull, which were later refloated and repaired. Around a coast of approximately 250 miles (400 km) an estimated 6000 ships have been wrecked, more than on any other comparable coastline of the British Isles. A traditional saying about the north coast is "From Pentire Point to Hartland light, A watery grave by day and night." The coast of the Lizard peninsula is particularly hazardous to shipping and the seaways round it were historically known as the "Graveyard of Ships".
