CARDIFF, WALES—While excavating Roman and Iron Age deposits at a hillfort outside Cardiff, archaeologists were surprised to discover ditches that contained Neolithic-period tools and weapons dating to around 3600 B.C. "Quite frankly, we were amazed,” Cardiff archaeologist Dave Wyatt, the excavation co-director, told Culture 24. "No-one realized the site had been occupied as far back as the Neolithic—predating the construction of the Iron Age hillfort by several thousand years." The number of broken flint arrowheads the team unearthed suggests that the site was a battleground at some point during the Neolithic. But according to team archaeologist Oliver Davis, events at the site were typically more peaceful. “The location and number of Neolithic finds indicate that we have discovered a causewayed enclosure – a special place where small communities gathered together at certain important times of the year to celebrate, feast, exchange things and possibly find marriage partners,”
