Discover Gelligaer & Merthyr Common

It's a designated Cadw Historic Landscape

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.
