The historic center of Morro d’Alba is characterized by a pentagonal city wall, consisting of high curtain walls and a scarp, whose most interesting feature is certainly the ancient walkway known as the “Scarpa.” The origins of this unique urban layout date back to the first half of the seventeenth century, when every available space within the castle began to be utilized. In fact, the feudal city walls were used as foundations for new constructions that eventually covered the old patrol walkway.

Today, the walkway is a highly evocative place, defined on one side by a long series of large arched windows overlooking the surrounding countryside, and on the other by the walls of the houses, where traces of ancient entrances can still be seen. The roof is marked by wooden beams of varying shapes and sizes.

This complex architectural structure, recently restored and returned to its former glory, also contains other points of interest in the underground structures located within it. A dense network of tunnels forms a veritable underground village that runs along the entire walkway, creating rooms of various sizes illuminated by small ventilation “windows” visible from the exterior walls of the Scarpa.
