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
