The castle Malaspina Dal Verme, is a fortified structure consisting of several buildings enclosed within the inner stone walls. Currently the castle has only the inner walls, the outer one having been demolished, together with the tower of Porta Nuova, in 1858, when the rectilinear wall called Porta Nuova was opened. The castle is equipped with a keep with hewn stone masonry set with a pseudo isodomic design. On the west side of the fortress are the remains of what is indicated as the Bishop’s tower. On the east side, in the corner of the boundary wall, there is a circular tower, equipped with two rooms. There are two entrances that allow access to the keep, to the south-east and north-west. The articulation and distribution of the interior of the donjon, whose first floor is significantly raised and much transformed compared to the original structure, especially following the interventions promoted by the last owner between the late nineteenth century and the first half of the twentieth century, is quite functional. The entrance hall leads to the "Sala delle Marine" and a living room with a large stone fireplace surmounted by the arms of the Dal Verme family. On the wall along the staircase leading to the upper floors, there is a detached fresco, referable to the sixteenth century, depicting a Madonna and Child.
