Tinkinswood Burial Chamber is a Neolithic tomb topped with one of the largest capstones in Britain. Measuring 24 feet (7 m) by 15 feet (4.5 m) and weighing as much as an articulated lorry, experts think it would have taken at least 200 people to hoist the massive stone into place.

Giant's Bite

Highlight • Viewpoint

High above the A470 to the north of Quaker’s Yard, the Giant’s Bite is a dramatic gap in the skyline quarried from the ridge top at the former Cefn Glas mine and quarry. ❤️👌
The site was intensively grazed up to the mid-1990s when a large belt of native trees were planted on the lower slopes.
These trees are now maturing and have helped to heal the visible mining scares. The shales forming the upper soil horizons support a wide variety of native flowering grassland species including wild strawberry, cowslip, foxglove and wild thyme, and the site is increasingly becoming re-vegetated by scrub species.
Incredibly Fine views of the Taff and Cynon valleys are afforded from the summit ridge, while the line of the former Glamorganshire Canal is also discernible.

The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

Ugly but kinda impressive grave - looks like concrete built... This Neolithic (New Stone Age) tomb is topped with one of largest capstones in Britain. Measuring a massive 24ft/7m by 15ft/4.5m and weighing around 40 tons (as much as an articulated lorry). Experts reckon that at least 200 individuals would have been required to hoist it into place. Excavations have uncovered the remains of over 50 people, along with broken pottery and flint tools. https://www.visitwales.com/de/attraction/historic-site/tinkinswood-burial-chamber-cadw-1843268
