You wouldn’t suspect that the lush, serene national gardens of Syntagma (which were the Royal Gardens of King Otto and Queen Amalia a few decades back) were the site of sophisticated Roman Bathhouse.
When works on a ventilation shaft for the Athens metro in the 1990s revealed these important finds, the shaft was moved to another location and the baths were excavated to reveal part of their now faded glory.
The large jugs seen today were clay silos for storing cereals, brought in by the Byzantine civilization (i.e. after the Roman civilization). The rest of this complex lies under the gardens and Amalias Avenue, so this must be seen as just a glimpse of what was once a mighty Roman bathhouse with a sophisticated system that the Romans once lavished in.
