Varazdinske Toplice
Roman baths excavated in the middle of a spa town that never stopped using the same springs.
Updated 30 August 2026
The Romans called this Aquae Iasae and built a substantial bathing complex on the springs, with a basilica, a forum and a temple precinct, developed from the first century and rebuilt after a fire under Constantine. Excavation from the 1950s onward exposed a large part of it in the middle of the modern town, so the Roman pools, hypocaust and column bases sit directly below the streets and beside a spa that has used the same water continuously since. Statues of Jupiter, Juno and Minerva found in the temple are in the local museum. The water comes out at around 58 degrees and is still used for rheumatology treatment.
