Patras is dotted with Roman monuments located in the historic city center and creating a unified archaeological site of great historical importance. These monuments are symbols of the growth of Patras during the Roman period and consist of the Roman amphitheater, the Roman nymphaea, the Roman aqueduct and the bridge of Meilichos.

The Roman amphitheater built in the 1st century AD century during the reign of Domitian is located near the Roman Odeon and is 200 meters long and 90 meters wide. The stadium hosted the "Caesarea", sporting events in honor of Caesar, on the occasion of 100 years from the foundation of the colony of Patras.

The nymphaea are examples of the intense Roman life, as they are buildings of the 4th century AD used as recreation areas. They had water jets, gardens, and were later used as temples and cemeteries.

The Roman aqueduct is located in the area adjacent to the fortress, in the form of an artificial dam and is now part of the modern reservoir. It is the area where the Nymphs, water deities, were worshiped in the antiquity. Its principle of operation was based on the principle of communicating vessels.


Το ρωμαϊκό υδραγωγείο, βρίσκεται στην περιοχή δίπλα στο φρούριο, υπό τη μορφή τεχνητού φράγματος και σήμερα αποτελεί μέρος της σύγχρονης δεξαμενής. Στο χώρο αυτό κατά την αρχαιότητα λατρεύονταν οι Νύμφες, θεότητες των υδάτων. Η αρχή λειτουργίας του βασιζόταν στην αρχή των συγκοινωνούντων δοχείων.
