Projects
In 2001 the Institute for the Protection of Cultural Heritage of Slovenia, Kranj authorized the Mengeš Museum to supervise machine excavation for the municipal infrastructure on Maistrova and Zadružniška streets in Mengeš since inhabitants had found some archeological remains. Only a few articles found their way to the Kamnik Intermunicipal Museum, which formerly had jurisdiction over this area. A total of 16 graves were excavated by December 2001: four inhumation and 12 cremations. One grave is attributed to the period after 600 AD, the stag tine characterizing it as the grave of an Avar soldier. The other three inhumation graves are presumably also from the same period
