The historic seaside town of Nafplio is located on the eastern Peloponesse peninsula of Greece. Nafplio (also spelled Nafplion or Nauplio) is accessible via an easy two-hour drive south of Athens. The town is close to the famous Bronze-age acropolis of Mycenae and Tiryns, both recognized as UNESCO World Heritage sites since 1999. The citadels are famous for the massive Cyclopean walls, tombs, and the immense collection of Mycenaean gold masks, engraved gems, and jewelry. The Mycenaean Greek civilization flourished during the last phase of the Bronze Age in ancient Greece, from around 1600 to 1100 BC. Several discoveries from that period are on exhibit at the Archeological Museum of Nafplio.
