The thermal waters emerge from the ground at a near-constant temperature of 54 degrees Celsius throughout the year.
The complex was constructed by the Romans to serve the military garrison stationed at the site of Forum Traiani.
The site contains evidence of distinct phases of construction spanning from the 1st century AD to the Byzantine era.
The original Roman hydraulic system utilized the natural pressure of the springs to circulate water through the various bathing chambers.
The archaeological site is built primarily using locally sourced pink and grey trachyte, a volcanic rock abundant in the Fordongianus area.
Excavations have uncovered votive offerings left by ancient patrons seeking healing from the therapeutic waters.
The facility was purposefully situated on the left bank of the Tirso River to utilize the natural geography for water management.
The site features a rare preserved example of a Roman 'natatio', or open-air swimming pool, integrated with thermal springs.
The Roman Baths of Fordongianus represent the archaeological remains of the ancient city of Forum Traiani, established during the Roman era to harness natural thermal springs. The site features an open-air bathing complex constructed from local pink trachyte stone. Visitors can observe the distinct tepidarium, calidarium, and frigidarium structures that were fed by water emerging at temperatures between 40°C and 54°C. An adjacent covered building houses remains of secondary baths dating from the Byzantine period. Archaeologists have identified complex hydraulic systems designed to channel volcanic water into the basins. The site serves as a testament to Roman engineering and the historical importance of therapeutic thermal waters in Sardinia. Its location on the banks of the Tirso River highlights the strategic integration of the ancient settlement with the landscape.

Bring a hat and sunscreen as there is very little natural shade within the exposed ruins.
Wear sturdy walking shoes to navigate the uneven ancient stone flooring and stairs.
Check the official website for current guided tour availability to access deeper insights into the hydraulic engineering.
Do not attempt to swim in the ancient Roman basins; they are for viewing only.
Operating hours vary by season; verify status for public holidays as the site may have limited access.
Avoid walking on or touching unstable archaeological walls; stay on designated visitor paths.
