A “once-in-a-decade” archaeological site has been uncovered in the United Kingdom at the Calthorpe Gardens residential development near Banbury, southern England.

The excavation, conducted ahead of new home construction, revealed artifacts dating back to the Mesolithic period (10000 B.C. to 4000 B.C.), including flint tools.

Additionally, researchers found remains of a small settlement from the Late Bronze Age to Middle/Late Iron Age and an Anglo-Saxon cemetery from the early medieval period, containing at least 52 individuals.

Notable discoveries include handmade pottery, textile tools, large enclosures likely used for animals, and roundhouses from the ancient settlement, Newsweek has reported.

The Anglo-Saxon burials yielded rich grave goods such as bead necklaces, pendants, personal objects, and weapons.
