Cloughmore, referred to locally as “The Big Stone” (from Irish a Chloch Mhór, signifying “the enormous stone”), is an immense stone found around 1,000 feet (300 m) over the town of Rostrevor, County Down, Northern Ireland, on a generally level territory of Silurian metasedimentary geography on the top side of Slieve Martin sitting above Carlingford Lough and the Cooley Peninsula in County Louth.
The rock stone, which has an ascertained mass of 50 tons, is a frosty sporadic, thought to have been transported from Scotland (from an island in Strathclyde narrows) and saved by withdrawing ice amid the last Ice Age. The Cloughmore Stone is typically the setting at Easter where the inhabitants of Rostrevor would as a rule go up and roll their Easter eggs down the slope. This has ended up kind of a custom for the Rostrevor inhabitants.
The famed local legend would lead you to believe that the stone was tossed from the Cooley Mountains, on the opposite side of Carlingford Lough, by the goliath of a giant Fionn mac Cumhaill.
