Cromlech du Pioch de Roumanis, Megalith and prehistoric stone circle near Balaruc-les-Bains, France

The cromlech du Pioch de Roumanis is an oval stone circle on a hill of the Massif de la Gardiole east of Balaruc-les-Bains, in the Hérault. It measures about 60 m across; the stones are 1.5–2 m wide and roughly 1 m high, some leaning, others lying overgrown on the ground. First described in the 19th century, it is the southernmost stone circle in the Hérault.

The cromlech was built around 5,000 years ago during the Neolithic period and was likely used as a gathering or ceremonial site. Over time, some stones have shifted or fallen, leaving the original circle only partially visible today.

The site is reached by narrow natural paths, so sturdy footwear and water are a good idea. Visiting during daylight hours makes it easier to see the size and texture of the stones clearly.

The circle measures about 60 metres across, the widest of its kind in the Hérault and the southernmost, first described in the 19th century. Its stones are 1.5 to 2 metres wide and roughly 1 metre high; some lean, others lie overgrown on the ground. About 2 km east, north of Frontignan, stands the Dolmen de la Coste.
