Opatovac (pronounced as /opǎːtovat͡s/, Serbian: Опатовац, Hungarian: Apáti, German: Sankt Lorenz) is a village in Croatia. It is connected by the D2 road. The village is home to one of the last remaining steppe grasslands in Croatia at the section of the Vukovar Plateau.[2]
The Serbian Orthodox Church of St. George was built in 1802 with the iconostasis dating back to 1769.[3]
During the so-called European migrant crisis the village hosted the temporary refugee camp where thousands of individuals received primary medical support and registration.[4]
