Maen Madog also called Maen Madoc is a standing stone in the heart of the Brecon Beacons National Park, about one mile north of Ystradfellte. It stands immediately beside the old Roman road known as Sarn Helen, just outside the Blaen Llia forestry plantation. A mile to the north is Maen Llia, a Bronze Age standing stone. The stone is not in its original location, and no grave has been found. Historians theorise that the burial remains were destroyed by the extremely acid soil. When Maen Madoc was recorded in 1805 it was recumbent. It was re-erected at some point in the 19th century and again in 1940. It is believed to have been erected in the late Roman period, possibly to mark the site of an early Christian burial. The southwest edge of the stone is inscribed with very worn Latin text reading 'DERVAC(IVS) FILIVS IVSTI (H)IC IACIT'. This translates loosely as 'Dervacus, Son of Justus lies here'. One theory says that Maen Madoc was a pre-existing Bronze Age standing stone that was simply re-used to mark a late-Roman burial site.

The views down onto Llyn Y Fawr from here is pretty spectacular. This is one of the nicest places in the Brecon Beacons to walk along. Once you have put in the effort to get here, the ridge has a good footpath, there's a nice walled shelter and the views down towards the lake is pretty awesome on a good day.

The route of the old tramway, once used by the local quarrying and mining works, now makes an enjoyable and atmospheric access trail to the mountains. It's used by both the Beacons Way and the Cambrian Way long-distance trails.
