Runnel Stone

The Runnel Stone is a submerged rock pinnacle located about one nautical mile south of Gwennap Head off the Cornish coast. The formation protrudes from the seafloor and rises significantly enough to pose a hazard to vessels in the area.

The reef caused at least 30 major shipwrecks between 1880 and 1923, including the SS City of Westminster which struck the rocks with tremendous force. This period marked the peak of maritime disaster along this section of coast before modern navigation systems were introduced.

The Runnel Stone represents a protected marine zone where the local fishing community and conservationists work together to manage the waters. This balance between tradition and protection shapes how people view the coastal waters today.

The area is marked by navigation buoys and markers maintained by Trinity House to alert passing vessels to the danger. Visitors interested in diving should plan for strong currents and tides that move swiftly around the rock formation.

Multiple shipwrecks rest on the seafloor around the rocks, creating an underwater graveyard that tells the story of maritime tragedy. Diving enthusiasts can explore these preserved remains and encounter the diverse marine life that now inhabits them.
