Casa de Gobierno de Corrientes, Government building at Plaza 25 de Mayo, Corrientes, Argentina

Casa de Gobierno de Corrientes is the provincial government seat in the city of Corrientes, Argentina, facing Plaza 25 de Mayo. The multi-story building follows an Italianate style with a central courtyard, arcaded galleries, and smooth columns that run along its facades.

The building was designed by engineer Juan Col, born Giovanni, and built between 1881 and 1886 by the Italian contractor Juan B. Buzzi. It stands on the site of the old Iglesia Matriz, built in the second half of the 17th century. It is one of the main examples of Italian architecture in Corrientes and opened the series of monumental buildings that shaped the city's historic area at the end of the 19th century.

The main frontispiece is framed by a curved element bearing the coat of arms of Corrientes, with lions at its sides. Above it rises the domed mansard roof of the Salón Amarillo, lifted over the roofline as an element of prestige. The raised exterior loggia serves as an official balcony or "palco oficial" over Plaza 25 de Mayo.

The building sits on the corner of Calle 25 de Mayo and Calle Salta, directly on the city's main plaza, making it easy to reach on foot from the city center. Since it functions as an active government seat, public access inside is limited, but the exterior can be viewed freely from the plaza.

The building stands on the same site as the old Iglesia Matriz, built in the second half of the 17th century; the government house has occupied that spot since the 19th century. The sources do not record any surviving remains of the church beneath the present building.
