Prehistoric workers probably exploited natural weaknesses in these structures, Parker Pearson said. These pillars are “the Ikea version of Neolithic megaliths,” Parker Pearson joked — the stones peeled off the outcrop as though from ready-to-use kits. “We’ve got dates for both quarries that link nicely with the first dates at Stonehenge,” Parker Pearson said. “It could be immediate, it could be 100 years from getting from A to B,” Parker Pearson said. Parker Pearson and his colleagues suspect that the stones were transported over land instead, on sledges.
