Still today, Cassino preserves monuments and places of high archaeological interest, which miraculously survived the cruel bombardments of WWII. The archaeological park of the ancient Casinum covers an area that goes from the National Museum “G. Carettoni” to the Abbey of Montecassino. The museum hosts the most significant findings of the area, from prehistory to the Roman period.

Located in the central part of the Roman town, the theater was built during the Augustan Era following the natural slopes of the hill, using the “bichrome opus reticulatum”. The building was brought to light in 1936 by the archaeologist Gianfilippo Carettoni and restored between 1959 and 1962.

The impressive mortuary building of the first century AD originally had two levels. It was built inside the urban area, against the sacred laws that forbade burials in inhabited areas. 

The roman Amphitheater was built in the second half of the first century AD just outside the urban walls, with an elliptical plan of rather limited dimensions (85×69 m). The building was intended for wild beasts hunting and gladiators fighting.

The Roman city was protected by massive polygonal walls that were 4.5 km long and surrounded a wider surface than the one effectively inhabited.

The structure known as Ponari’s Nymphaeum, by the name of the property owners, comprises two adjoining rooms. The first one had a rectangular shape and a barrel vault made of opus caementicium with rectangular niches along the walls, while the second one was a small roofless atrium provided with an impluvium at its center. The nymphaeum used to host water games and was part of a rich private residence.
