 The most famous project of the Mycenaean era was the network of roads in the Peloponnese . This appears to have facilitated the speedy deployment of troops ; for example , the remnants of a Mycenaean road , along with what appears to have been a Mycenaean defensive wall on the Isthmus of Corinth . The Mycenaean era saw the zenith of infrastructure engineering in Greece , and this appears not to have been limited in the Argive plain .
