Casa Scaccabarozzi, Neoclassical residential building in Vanchiglia district, Turin, Italy.

Casa Scaccabarozzi is a neoclassical residential building at the corner of Corso San Maurizio and Via Giulia di Barolo in Turin's Vanchiglia district. Its trapezoidal plan narrows to just 54 centimetres on one side, while the opposite facade measures 4.35 metres. The facade is painted in bands of ochre yellow and dusty rose pink, divided by pale pilasters and cornices, with tall rectangular windows fitted with dark louvered shutters and small balconies enclosed by black iron railings on stone supports.

Alessandro Antonelli received the small corner lot as payment for his work for the Vanchiglia Constructors Society. When negotiations to buy the neighbouring plot failed, he built an income property with one apartment per floor, adding the first four floors in 1840, two more later, and the top floor in 1881. He named it after his wife, Francesca Scaccabarozzi, and the couple lived there briefly before moving to Via Vanchiglia 9.

Turin residents call it Fetta di Polenta, slice of polenta, for its ochre-yellow paint and trapezoidal plan. The building was also known as Casa luna and la spada. Its ground floor once housed the Caffè del Progresso, a meeting place for Carbonari and revolutionaries.

Access to the building is through entrances located at the street corner, though the interior has limited space due to its narrow staircase design. A rope-and-pulley system on the roof allows residents to move large furniture and objects through the windows.

The 54-centimetre wall facing away from Corso San Maurizio hides a shaft that Antonelli used for the chimney flue, water pipes and, originally, the toilets of every apartment. A pulley on the top floor, still visible from Via Giulia di Barolo, was fitted because the narrow stone scissor staircase cannot take bulky loads.
