Cover it! The Protection of a Merovingian Burial Ground in Borgharen (Municipality of Maastricht), the Netherlands

A Merovingian burial ground in Borgharen was threatened by development. Plans however could be changed so the site could be preserved. The initial research however showed the bone material was at risk of severe degradation in the near future. In order to determine whether in situ preservation was feasible three campaigns were carried out. This led to the conclusion that the burial conditions were excellent and there was little risk that severe degradation will reduce archaeological information of the site over the coming decades. The remaining threat concerned illegal excavators with metal detectors and spades. To protect the site it was covered with a series of different materials to prevent the site from being looted.
