Gilwern Hill is a hill of 1,436 ft about three miles south-east of Llandrindod Wells in Radnorshire.

Geology

The hill is composed from a range of lower and middle Ordovician volcaniclastic rocks which form a part of the Builth Inlier. Palaeontologists Pete Lawrance and Brian Beveridge have spent 30 years examining fossils from a privately owned limestone quarry on the hill. Amongst fossils so far identified at this location are the trilobites Meadowtownella, Bettonolithus, Protolloydolithus and Anebolithus together with Conulariida, Iocrinus, Clonograptus and starfish

Stone rows

There are two prehistoric stone rows at the southern end of the hill, each with a large stone, more than six feet high, at one end.
