Manacles, Cornwall
Historical Description
Manacles, a group of rocks off the SE coast of Cornwall, near the shore of St Keverne parish, and 10 miles SSE of Falmouth. They rise but slightly above water, have sunk rocks near them, and are dangerous during an E wind and ebb tide. The emigrant ship John was wrecked on these rocks in 1855, and 191 of the total persons on board were drowned.
