The HMS Primrose was a sailing gunship that hit the Manacles in 1809. Over the years it has been subject to various types of salvage, many times. What remains now are just a few cannon balls and some encrusted items. Every now and then something new is found but nothing of any great significance fr a long time.
At the church in St Keverne there is a carronade, removed from the HMS Primrose, it is visible from the road in front of the church.
Wessex Archaeology recently surveyed the Primrose, trying to work out if it was worth protecting, along with our help. They decided there wasn’t enough left to designate it as a protected site.
