The National Archaeological Museum of Palestrina is housed in the Renaissance Barberini palace, on the top of the ancient sanctuary of Fortuna Primigenia. In the rooms of the Museum, the most important finds from ancient Praeneste and its territory are exhibited, sorted by major themes that embrace the main aspects of the history, culture and artistic productions of one of the most important and flourishing cities of ancient Lazio . The rooms on the first floor house works relating to the cult of Fortuna - such as the head of the cult statue of the goddess, found in the Sanctuary inside the so-called well of the sortes, and the colossal statue of Isis-Fortuna, a Hellenistic original in gray marble from Rhodes, Roman copies of Greek masterpieces, honorary statues, portraits and reliefs from the republican and imperial ages. One of the famous Grimani reliefs dates back to the Augustan age, an admirable artistic expression of the Augustan political program of pacification and rebirth, perhaps the work of the same sculptors who decorated the Ara Pacis in Rome. On the second floor are exhibited materials found in the necropolis, including cysts and bronze mirrors adorned with refined engraved decorations depicting rare versions of ancient Greek and Italic myths, and numerous votive and architectural terracotta from the city's sanctuaries. On the third floor a single room houses the grandiose polychrome mosaic of the Nile, a perspective view of the Egyptian landscape during the flooding of the Nile, created by Alexandrian artists at the end of the 2nd century BC. It is one of the largest and most important Hellenistic mosaics preserved. an absolute masterpiece for composition, chromatic taste and richness of details. In the archaeological area in front of the Museum it is possible to visit the imposing remains of the sanctuary of Fortuna Primigenia, structured in a series of artificial terraces connected by ramps and stairways. It represents the greatest example of Hellenistic architecture in Italy, inspired by the monumental scenographic complexes of the Eastern Aegean.
