Basilica Therma Basilica Therma is an ancient Roman spa located in Sarikaya town of Yozgat province and it is about 80 km far from the city center. The bath has been in use for centuries. The first records show that it was built in 2nd century AD and was used in Byzantine, Seljuk, and Ottoman periods and is still open to the public. The large thermal pool measures 23,30x12,80 meters. It has a depth of 1.34 meters and the water is about 45°C (110 F). There is an inner pool measuring 16.00x4.00 meters with symmetrical ladders on its both sides that extends into the larger swim area. The third pure-thermal heated pool with boiling hot water from the ground is positioned perpendicular to the other two pools and measures 15.00x5.20meters semi-circular shaped with short linear extension in its short linear angle measurement ends. Even though, there are 3 pools now, it is confirmed by the scientists that it is a complex consisting of 7 pools. Basilica Therma is one of the 2 Roman baths in the world, with a history approximately 2,000 years old. Though it may seem unusual to see bull's heads on pillars and snake symbols engraved into stone, these features are actually significant. Bull’s heads were emblems that symbolize Rome’s power, while snakes mouth represents Asclepius (the god who regulates human health) as well as Hermes (a Greek deity associated with knowledge). These symbols signify why this was once used as an ancient thermal treatment center—to heal patients by submerging them in warm water. It is believed to be the oldest thermal treatment center in the world. Basilica Therma has been added to the Tentative List of UNESCO in 2018.
