The tower was originally one of several access gates in the city's defensive walls, but it is the only one still standing today.
It is constructed from local sandstone, commonly referred to as 'pietra arenaria'.
The name 'San Cristoforo' was adopted later, replacing its original designation as the Portixedda gate.
During the 19th century, the tower was repurposed as a jail, with internal modifications to accommodate cells.
The structure features a unique dual-facade design, with the side facing the countryside being flatter than the side facing the city.
It is the historical entry point for the procession of the Sartiglia, Oristano's most famous traditional equestrian festival.
The Tower of Mariano II, also known as the Torre di San Cristoforo, served as the primary defensive gateway into the medieval city of Oristano. Constructed in 1290, this sandstone structure was part of a larger defensive wall system commissioned by Giudice Mariano II. It stands 19 meters tall and features a square plan with two distinct elevations. The tower was integrated into the city's fortifications to protect against incursions during the reign of the Judicate of Arborea. In later centuries, the structure served as a prison, transitioning from a military fortification to a civilian detention site. It remains one of the few surviving remnants of Oristano's ancient defensive perimeter. The structure underwent significant restoration to preserve its original masonry and layout. It is located at the center of Piazza Roma, marking the historical threshold between the old town and the modern city. The tower stands as a symbol of Oristano's period of political autonomy under the Judicate.

Walk the full circumference of the square to observe the architectural differences between the inner and outer faces of the tower.
Combine your visit with a walk through the adjacent historic center streets to see the contrast between medieval and modern urban planning.
Check local event calendars to see if your visit coincides with the Sartiglia festival, when the tower plays a central role.
Do not expect a large, multi-room interior museum; the experience is primarily focused on the exterior architectural history.
Occasionally closed for maintenance; access to the interior is limited and seasonal.
