The building that houses the Archaeological Museum is one of the most luxurious Venetian buildings in the city and marks the end of the so-called "Great Road".

The upper two floors house the Archaeological Museum, while the lower one houses the 4th Ephorate of Prehistoric and Classical Antiquities. The museum houses many exhibits dating back to the Paleozoic and Mesozoic eras.

The collection of archaeological finds reflects prehistoric times and finds made in Mycenae and throughout the Argolis. The collection also includes excellent pottery from the early Mycenae period. The most important exhibit of the museum is copper armor dating back to 1450, a unique discovery made in a burial in Dendra, along with weapons and other items of the deceased leader. On the second floor of the building, among the exhibitions, you can get acquainted with the weapons and helmet of a warrior of the post-Mycenaean time. The halls of the museum display priceless collections of pots and weapons from Asini and Tiryns, as well as statuettes and other items from the ancient temple at Tiryns.
