Argos: Europe's Oldest Continuously Inhabited City
Argos is considered the oldest city in Greece and one of the oldest continuously inhabited cities in all of Europe. Unlike Mycenae or Tiryns, which are abandoned archaeological sites, Argos is a living city today — its monuments sit literally within the urban fabric.
The Ancient Theatre
Built in 320 BC at the foot of Larissa hill, the Theatre of Argos had a capacity of roughly 20,000 spectators — one of the largest ancient theatres in all of Greece. It was renovated around 120 AD. For centuries it hosted the musical and dramatic contests of the Nemean Games, as well as games in honour of the goddess Hera.
The Roman Agora and Baths
Directly across from the theatre lies the ancient agora, with well-preserved Roman baths (also known as the Serapeion-Asklepieion) attesting to the city's luxury during the Roman period, with elegant details, elaborate mosaics, and statues.
Hadrian's Aqueduct ("Kritirion")
A Roman water-supply structure, one of the region's most significant engineering works.
Aspida Hill
Home to a prehistoric (Middle Helladic) settlement, along with the sanctuaries of Apollo Deiradiotis and Athena Oxyderkis, and chamber tombs.
Larissa Castle
Built as early as prehistoric times atop the acropolis hill, dominating the city below.
The Heraion
8 kilometres from the city stands the Heraion, a sanctuary dedicated to Hera, patron goddess of the city-state of Argos — its official religious centre, despite the distance.
