Despite at first glance appearing deserted there is more to Gelligaer than meets the eye – its complex history of fact and legend has left interesting Roman and Medieval remains.
Among its gems are the interesting Roman and Medieval remains, a megalithic burial mound at Carn Bugail, the Cen Gelligaer Stone and the remnants of Capel Gwladys, the mother of Tydfil the Martyr from which Merthyr Tydfil gets its name.
Gelligaer and Merthyr Common is an upland landscape in South East Wales, divided between the county boroughs of Merthyr Tydfil and Caerphilly. The Common is a living and working landscape, steeped in history.
It is designated Cadw Historic Landscape due to evidence of continued land use and activity from prehistory to the recent past.
