Museo Palacio Dionisi, Photography museum in Córdoba, Argentina

Museo Palacio Dionisi is a photography museum in Córdoba occupying a spacious building with multiple exhibition halls. The rooms display diverse photographic collections and contemporary artworks arranged to showcase different styles and periods.

The house was built between 1920 and 1924 for the ironmonger Juan Kegeler, designed by the architect Miguel Arrambide. It later passed to Kegeler's daughter Margarita and her husband, the physician Humberto Dionisi, who founded the Instituto del Cáncer at the Hospital de Clínicas and was one of the doctors who diagnosed Eva Perón. After serving as the seat of the Secretaría de Cultura de Córdoba, it was restored by the Dirección General de Arquitectura de la Provincia and opened as a museum on 25 July 2013. In 2018 the provincial legislature passed Law 10.578 creating the Museo Provincial de Fotografía Palacio Dionisi.

The museum's name honours Humberto Dionisi, the gynaecologist who diagnosed Eva Perón and founded the Hospital de Clínicas cancer institute. Its Sala Cero invites three artists each year to curate the next, while Sala Documentos draws on public and private photographic archives. Since 2019 an open-air gallery has shown temporary shows on the perimeter railings of the Palacio Ferreyra and in Parque Las Tejas.

The museum is located on Avenida Hipólito Yrigoyen and offers guided tours along with rotating exhibitions. These changing displays allow visitors to discover new works each time they return.

The entrance hall holds a stained-glass window made by the firm Villela y Thomas, and the central patio is covered by a coloured iron-and-glass skylight. The house was built between 1920 and 1924 for the ironmonger Juan Kegeler; his daughter Margarita married the doctor Humberto Dionisi, one of the physicians who diagnosed Eva Perón.
