what is the relevance of the city of piraeus as the place of dialogue in the replublic

A brief explanation:

"It is not surprising that Socrates meets the challenge of democratic politics outsidethe city and specifically in Piraeus. Architecturally, Piraeus was the embodiment of theurbanistic rationalization of the isonomia, the principle, which was one of the mainconstituting significances of Athenian democracy. The city was planned and built following the principle of proportional equality. The second aspect is Piraeus’ distanc efrom the city. One needs to have a distance from an object in order to observe it. This distance reinforces the presence of the object and, paradoxically, minimizes its proximity."
