Awe inspiring building. One of the most iconic of Spello; it seems like time has never passed. Really a must-see attraction.

Porta Venere was erected in the Augustan age and included in a considerable number of buildings. The tower-gate complex has been the object of at least two restorations: in the years from ten to twenty, when many buildings of the Middle Ages were demolished, and again in the years 1940-1941. Porta Venere is closed on the sides by two towers called "Properzio" with a dodecagonal plan. Made typically of three arches, it is decorated with Doric pilasters, interposed between arches. In the upper part there is a trabeation along the entire length of the door, a unifying motif in the sign of a compositional harmony. It is also equipped with a cavaedium, a fortification building that provides a double door. The whole area on which the complex stands today was once full of other buildings whose remains can now be seen in the cellars of the houses that run along Via Torri di Properzio .
