Drensko Rebro is the site of two known
mass graves from the end of the Second World War. They both contain the remains of Croatians that were disarmed and murdered in May 1945 along the road to
Virštanj and at the crossroads between Drensko Rebro and
Lesično. The House No. 8a Mass Grave () is located north of
Pilštanj, between a roadside ditch and a slope. The Sušica Creek Mass Grave () is located in a meadow between Sušica Creek and the road to Pilštanj, between electric poles numbered 41 and 42. ==References==
