The Castle of Morro (Castrum Murri), built exclusively for military purposes, was transferred in 1213 from Senigallia to Jesi, thus becoming part of its territory. These ancient walls, which enclose the historic village and La Scarpa, have a pentagonal layout and consist of high curtain walls with a scarp.

Walking along the walls and passing through the entrance gates is a unique experience that makes you feel immersed in history. Along the perimeter of the city walls rise two panoramic towers (all towers are named in connection with the territory and its history) and the La Scarpa walkway.

Small windows also allow air to flow into the underground tunnels.
