Built around 200 CE, the Great Baths of Dion cover 2,100 m² and showcase the height of Roman social luxury. The complex is famous for its advanced hypocaust heating and the group of statues depicting Asclepius and his children discovered in the north wing. Though destroyed by earthquakes in the 4th century, its marble-paved rooms and brick furnaces remain a masterpiece of Roman engineering. Dion Archaeological Site, Macedonia, Greece.
