Boyne to Brodgar

At https://archaeologynewsnetwork.blogspot.com/2019/08/archaeologists-disco… … the 'Boyne to Brodgar' project has come up with around 40 previously unknown monuments in the vicinity of Newgrange – including one that aligns with water solstice sun rise and predates Newgrange. The sites range from the early Neolithic, around 4000BC, until the Bronze and Iron Ages, even as late as the early medieval period. The survey made use of satellite baseed remote sensing, drones, airborne laser scanning and geophysics.
