When exploring the Eastern Peloponnese I based myself in Nafplio. Three components of the tentative site are in town, one in the bay on an island. and two on hills overlooking the town

These fortifications were important as they were used by the Byzantines and later the Venetians to foster trade. Being accessible by sea, they could be supplied from sea and could keep their independence, even if the land outside the city walls was governed by a different entity, e.g. Slavs, Arabs or Ottomans.

OUV

While the fortifications in and around Nafplio are nice, they pale in comparison to Rhodes and Corfu. Corfu is the Venetian fortification in Greece. Rhodes is the crusader castle. Both are already inscribed. I don't see what inscribing them a second time would bring as benefit. Nafplio on it's own would not make the list. And looking at Ilya's review, neither would the Crete ones.

Getting There

For Rhodes and Corfu, see their respective page. For Nafplio, you have frequent connections to Athens by bus and one connection per day to Tripoli.

While You Are There

Nafplio is a pleasant town and a good base to visit the two WHS in the area (Mycene and Epidauros). In Argos, you also find another serial tentative site in the amphitheatres of Greece.
