Tremerje is the site of a mass grave associated with the Second World War. The Savinja Mass Grave (Slovene: Grobišče ob Savinji) lies along an unpaved road along the Savinja River, on an overgrown part of the riverbank near a fork in the road by an embankment. The grave contains the remains of six civilians from Celje.[4]
