Excavations have brought to light the Asklepieion of Corinth which was located to the north of the Theatre and 400 meters away from it.  A temple had been built in the middle of the yard which was connected with a square yard with a peristyle in it and arcades along its four sides. This second yard belonged to a spring called Lerna.
A long pillar of a colonnade was obvious even before excavations to the south of the Asklipeion. It belonged to the Gymnasium of the town.
The architectural style of these buildings lead archaeologists to the conclusion that the ruins that have been excavated belong to the era of the Roman Empire. Only a few remains from the ancient world have survived after the destruction of Corinth in 146 BC. They include a periptere Doric temple which was reconstructed during the roman era, a sacred spring  to the south of the temple as well as the initial core of the springs of Peirene kai Glauce. A few remains of a stadium to the south-east of Peirene, a small temple in the middle of the west side of Apollo’s yard  as well as the north and the south arcades, are the only findings that date back to the classical era.
The architecture of Corinth, after its reconstruction, was based on the roman style. Some ancient buildings were repaired or rebuilt according to the needs of the roman architecture. Peirene and Glauce springs took a monumental shape after their reconstruction.
