From 1942 to 1944 there was a quarantine camp of war refugees located in Põllküla. The refugees were mainly Finns from Ingria, but also other minorities (Estonians, Latvians, Russians) living in then German-occupied Leningrad oblast. Similar evacuation camps were also in nearby Klooga and Paldiski. The refugees who died in the camp waiting for further evacuation were buried in unidentified mass graves in and around Põllküla. Now there is a memorial for those who died in the camp. In the summer of 2018 a memorial tablet was opened in honor of the leader of the evacuation of the Finns, professor Pentti Kaitera [fi].
