Harmantepe Kalesi

Harmantepe Castle, located to the north of Adapazarı Harmantepe Village, was built on a small natural hill. While its surroundings were marshy and swampy, they were later transformed into fertile agricultural land thanks to the canals opened on both sides. To reach the castle, it is necessary to turn onto the field road branching off to the left from the road going from Küçük Söğütlü to Akçakamış Village. Access is a little difficult in rainy weather.
