Todurge Rock Caves & Lake The village of Todurge, now known as Demiryurt, is situated in the Zara district of Sivas province, and is famous for the lake named after it, which is a popular tourist destination in Sivas. The Todurge rock shelters are located in the steep northern part of the village, carved into the rocks. Over 100 of these caves, known for their beauty, were created by digging side-by-side and under one another. These rock caves are distributed across various small spaces and showcase exceptional craftsmanship. The walls of the caves in some areas are made of stones and khorasan cement with observation holes. The history of the Tödürge village caves dates back to the Iron Age (1200-750 BC). Some of the caves have a cross sign, indicating their use during the hiding period of Christianity in the 2nd and 3rd centuries.
