The Acropolis of Argos above the plain of Argolis
A fortress between antiquity, the Middle Ages and panoramic views…
High above the city of Argos, Larissa Castle rises on a striking rocky hill – one of the most historically significant hilltop castles in the Peloponnese. The complex is visible from afar, standing like a stone guardian over the fertile plain of Argolis. The site was originally the acropolis of ancient Argos and was repeatedly fortified, expanded, and used over many centuries.
Today, visitors can expect a sprawling ruin and fortress complex in which traces of ancient walls, Byzantine structures, and Venetian-Ottoman alterations overlap. The castle was in use for almost two millennia and is therefore among the most enduring fortified sites in Greece.

Plan about 1–2 hours for your visit to the castle.
The best way to reach the castle is by car; parking is available on site.
With sturdy, good footwear, the castle is much easier to explore.
There is very little shade, so be sure to bring a hat and plenty of sunscreen.
The complex on the hill
Larissa Castle spreads across several levels of the hill, following the natural topography. At the top lies the actual citadel with the strongest fortifications; below it, rings of walls, towers, and former functional areas descend the slope.
As you climb through the complex, you move through a sequence of stone paths, wall remains, and open plateaus. Again and again, sweeping views open up over Argos and the entire Argolis plain – all the way to the mountains of the Peloponnese.
The present structure of the castle dates mainly from the Middle Ages, but it is based on much older fortifications, some of which go back to antiquity.
History in layers
The history of Larissa reaches back to prehistorical times, when the hill already served as a fortified lookout and defensive position. Over the centuries, it was used by Greeks, Byzantines, Franks, Venetians, and Ottomans, and was repeatedly rebuilt.
It was especially in the Middle Ages that the castle took on its present form as a strategically important hill fortress. Towers, rings of walls, and an inner core area were added, while older structures remained integrated into the fabric of the building. During the Ottoman period, the complex remained militarily relevant before losing its function as a fortress in the 19th century.
Today, parts of the fortification walls, a cistern, and remains of a small castle chapel are still visible, giving an impression of its former use.
Visiting the castle
A visit to Larissa Castle is less a classic tour and more a small hike through history and landscape. The path up is stony and partly steep, but easy enough to walk. Along the way, shaded sections alternate with open areas where the sun bathes the old walls in warm light.
Once at the top, a wide view opens over Argos – one of the oldest continuously inhabited cities in Europe – and the surrounding plains of Argolis. The combination of ruins, nature, and panorama makes the place especially atmospheric, particularly in the early morning or late afternoon.

A place between antiquity and the Middle Ages
Larissa is not a “finished” monument, but a fortress landscape that has grown over time. Ancient foundations, Byzantine extensions, and Venetian and Ottoman alterations visibly overlap here, making the castle a living history book in stone.
Anyone who climbs the hill experiences not only an archaeological site, but a place where the history of the entire Argolis region can be read in several layers.

The view over Argos
Particularly impressive is the moment when you stand on the upper platforms and let your gaze wander over the city and the vast plain. Larissa Castle combines exactly this impression: historical depth, expansive scenery, and the quiet presence of a place that has held significance for millennia.
A visit here is therefore not a quick detour, but a peaceful walk through time – high above one of the oldest cities in Greece.
