Balduina is a residential neighborhood in the Municipio XIX of Rome, Italy. Situated on the southern side of Monte Mario at 456 feet (139 meters) above sea level, it is highest part of the city. Modern Balduina began with a few elegant villas around 1909, and a much bigger expansion occurred after World War II with a boom of typical Roman Palazzines — four- or five-story buildings, divided into apartments.
