Palacio Ariztía, Venetian-style palace in Viña del Mar, Chile.

Palacio Ariztía is a Venetian-inspired palace building in Viña del Mar with two stories, a basement, and a prominent tower section. The facade is defined by columns at the entrance gallery and displays the elaborate European craftsmanship of that period.

Rafael Ariztía, a businessman and politician, commissioned the palace from Italian architect Ettore Petri after the 1906 earthquake. The Ariztía family kept it until the late 1940s, when businessman Juan Molfino bought it. In 2000 it became the regional headquarters of Junji, and since 2003 the International Institute of Culinary Arts and Services has managed the building.

The building reflects the European architectural style that wealthy Chileans favored in the early 20th century. Visitors can still see today the detailed architectural elements that show this international connection.

The building is located in Viña del Mar and currently serves as headquarters for the International Institute of Culinary Arts and Services. Visitors should be aware that access may depend on the building's current institutional use.

The building passed from the Ariztía family to businessman Juan Molfino at the end of the 1940s. In 2000 it became the regional headquarters of Junji, and since 2003 the International Institute of Culinary Arts and Services has administered it. The 1985 earthquake damaged its ceiling, which was replaced with a lighter structure.
