Men Gurta, or St Breock Downs Monolith as it is commonly known. This imense lump of quartz streaked granite is the biggest and heaviest standing stone in Cornwall.
It measures over 10ft (3.5m) tall and weighs in at around 16 toms.
The Late-Neolithic or Bronze Age (3500-1500 BC) stone fell over in 1945, and was re-erected in 1956. Excavation of the site revealed quartz pebbles and 2 hollows, findings that have been linked to burials at other sites.
