Wander the ruins of this ancient fortress to enjoy unrivaled views of Nafplio’s historic Old Town and the northern bay of the Argolic Gulf.

Rising out from a headland above Nafplio’s Old Town is the ruined castle of Acronafplia. Stroll around the castle’s ramparts to spot the remnants of centuries-old monuments. Enjoy views back across Nafplio’s historic center and marvel at the sunsets over the Argolic Gulf. Acronafplia is the oldest of three castles located in Nafplio, built over hundreds of years by the Romans, Venetians, Franks and Turks.

The eastern section of the castle is its best preserved. Here, the ruined walls are believed to date back to the Hellenic period and Byzantine Empire. Gaze up at the thick walls, which present an interesting backdrop to the city. Walk to the western side of the castle, where the walls provide evidence that Nafplio has been a fortified city since around 400 B.C. Check out the hotel, which stands on the site of a former military barracks, hospital and prison.

Go to the far westerly tip of the headland to see the bastion known as Pende Adelfia (The Five Brothers). The name relates to the five well-preserved canons that point out into the surrounded bay.

A major highlight of visiting the castle is to enjoy the panoramic views. Spot major Nafplio attractions such as the Castle of Bourtzi, the Fortress of Palamidi and Syntagma Square, in the heart of the Old Town. The views are particularly impressive at sunset when the sun disappears behind the mountains of Arcadia. Visit in fall when a cactus forest on the western slopes of the headland springs to life with yellow flowers.

Situated on the southwestern corner of Nafplio, Acronafplia is easily reachable from all parts of the city. It’s about a 10-minute walk from Syntagma Square and Arvanitia Beach. An alternative way to see Acronafplia is to walk along the Arvanitia Promenade. This coastal pathway runs around the base of the castle from Arvanitia Beach to the Port of Nafplio. 

The castle is open daily and entry is free.
