In June-August 2010 large scale excavations were executed on the cemetery belonging to the monastery, an area now termed the Paardenmarkt, by Hollandia Archeologen in cooperation with Leiden University. During the course of nine weeks, the students from the former minor Human Osteoarchaeology excavated and cleaned over 180 single coffin burials and 20 secondary inhumations. Interestingly, also two mass graves dating to the Siege of Alkmaar with 9 and 22 individuals were encountered. All the remains are housed in the Faculty of Archaeology, Leiden University and are currently undergoing the osteological analysis.
