The Manacles

The Manacles is a group of submerged rocks and reefs stretching about 1 nautical mile east and southeast from Manacle Point into Falmouth Bay. The area is riddled with sunken vessels and attracts experienced divers interested in exploring underwater wrecks.

The location has been a ship trap since the 18th century, with more than one hundred documented vessel losses including HMS Primrose in 1809. This pattern of shipwrecks continued over two centuries, making it a major maritime graveyard.

The name comes from Cornish "Meyn Eglos", meaning church stones, referring to the visible St Keverne church spire from this location. These rocks are deeply woven into local identity and shape how residents think about their coastline.

Access is only by boat from the nearby coast, and the site is suitable only for experienced divers familiar with strong currents. Weather conditions change quickly in this exposed location, so checking conditions beforehand is important.

The surrounding marine conservation zone protects rare Maerl beds, a special algae type that feeds juvenile sea animals and supports a fragile ecosystem. These habitats are often overlooked but make the location significant for marine biology.
