Hej, It's still possible to find Clovis, there are clues whereabout he was burried, but the church under which he was supposed to rest was modified, destroyed... and noone knows for sure what was built or rebuilt in ancient times so the tomb could be under some building or even under the road. The tomb effigies were all rebuilt and put on display in St Denis but for a lot of Merovingian and Carolingian kings were not in St Denis, it could be that the tombs themselves were not destroyed during the french revolution (they could have been destroyed before it, too, though) because their location were lost already, then (a lot of them, after the viking raids, long before 1793). The effigies were destroyed but not necessarily the tombs. Here is a link (in french) listing the kings and where people think they were burried : http://saintdenis-tombeaux.1fr1.net...-inhumes-hors-de-saint-denis-et-hors-de-paris But even in St Denis there are undisturbed old (Merovingian ?) tombs which were not digged by archeologists either, in the layer where Arégonde was found.
