Casa Maioli (later Stanghellini) is one of the best preserved Venetian Renaissance style buildings dating back to the 15th century in the city of Ravenna. The current building has undergone numerous alterations in the sixteenth century that have drastically changed the original structures partially visible on the facade and inside. The building is located at street number 8 of Via Paolo Costa, opposite the impasse San Nicandro.
The current building consists of two adjoining buildings of different heights and an internal courtyard with garden and well with a real limestone Venetian blind. The external wall curtain made with exposed bricks consists of two slightly oblique sections whose junction is visible on the left of the main entrance. The portal is made of Istrian stone with a round arch resting on two renaissance corbels; the lintel bears a scroll with the monogram of Christ, probably in place of an older heraldic coat of arms. The left-hand building is crossed by an external flue with a hexagonal brick section that originates at the level of the first floor with an elegant overturned spire formed by small round bricks imbricate cantilevered. This structure is surmounted by a circle of three brick panels, each enclosing a coat of arms emblem, once probably depicting a painted weapon, now no longer visible. The chimney cap, also hexagonal, ends with a cusp of conical section formed by a series of shaped elements in terracotta. The windows of the first floor have probably been made to replace the original presumable circular shape. The second floor of the left side of the building has two mullioned windows with columns, capitals and Renaissance arches. The round arch overlooking the mullioned windows is made of worked terracotta. The cornice that supports the roof is made with a series of brick elements to function as a support that form a characteristic decoration with teeth. The entrance is divided by a large hall with a wooden coffered ceiling and double beams, with pictorial decorations with geometric and floral motifs. The access to the main floor is given by a large staircase on the left leading to a large well-lit room with double exposure on Via Paolo Costa and the internal garden, which recalls the "portego" of the coeval residences of Venice. The wooden ceiling of the living room is also made with wooden drawers resuming the style of the entrance hall, although much richer and more elaborate. The second floor has a ceiling with a warp formed by wooden beams and terracotta tiles as well as the large rooms of attic characterized by high heights, probably destined for warehouse use.
