Aquae Iasae

Aquae Iasae, located in present-day Varaždinske Toplice, Croatia, was a significant Roman settlement and bath complex renowned for its healing thermal springs. Initially inhabited by the Illyrian tribe Jasi in the 3rd century BCE, the area gained prominence under the Roman Empire between the 1st and 4th centuries CE. The settlement featured a public area on a hill terrace with Roman architecture, including bathing complexes, a forum, and temples dedicated to Jupiter, Juno, and Minerva. The site faced destruction during a Gothic incursion in the late 3rd century CE but was restored by Emperor Constantine in the 4th century CE. However, it ultimately succumbed to the invasions of the Migration period. Today, it stands as one of the best-preserved Roman archaeological sites in Croatia, offering insights into ancient Roman religious and civic life.
