This underground settlement which is located in the centre of the village of Ozluce, the ancient name of which was Zile, is on the Nevsehir-Derinkuyu road, 6 km south of the town of Kaymakli.
Ozluce Underground settlement is different from the others in terms of its geological formation and architectural features. The underground settlement has tufa of different colors. There is only one floor in this underground settlement which has not been completely opened; however, it covers a very large area.
At the entrance is a place with two intertwining arches made of basalt. Access to the main tufa stone can be gained through a 15 m long passage, made of rubble stone. The stone places, which lead to the underground settlement, are more recent than the rock hollowed places that form the underground settlement. At the end of this passage there is a millstone door which is made of hard granite and is 1.75 m in diameter.
Being the largest area in the underground settlement, the main space at the entrance consists of two parts. To the right of the main space are storage rooms, and to the left are living areas. On the sides of the long corridors are cell-like rooms and on the floor are traps.
