Visit Ancient Corinth and the archeological museum.
Ancient Corinth was one of the largest and most important cities of Greece, with a population of 90,000 in 400 BC. The Romans demolished Corinth in 146 BC, built a new city in its place in 44 BC, and later made it the provincial capital of Greece.
Acrocorinthis, the acropolis of ancient Corinth, is a monolithic rock that was continuously occupied from archaic times to the early 19th century.
Tip: if you love natural landscapes you can spend one more day before heading up to Epidaurus for a visit at Lake Doxa near Corinth
