Juan Carlos Castagnino Municipal Museum of Art, Mar del Plata (must see)

The Juan Carlos Castagnino Municipal Museum of Art is the premier museum of fine arts in Mar del Plata. Commissioned by the Ortíz Basualdo family of Buenos Aires, among the most prominent landowners in Argentina, the distinctive villa on Mar del Plata's prestigious Stella Maris Hill was built in 1909 as a summer residence. Designed by Luis Dubois and Pablo Pater, the eclecticist, Art nouveau villa followed a picturesque movement in French architecture common to new, upscale residences in both France and Argentina, at the time. The structure, predominantly in stone, was capped by zinc mansard roofing.

The oceanfront city was given its first municipal museum of fine art in 1938, when the facility was inaugurated in the Mar del Plata City Hall. The museum gathered a collection of mainly modern art in subsequent decades, and in particular works by local realist painter and muralist Juan Carlos Castagnino. The museum's collections feature nearly 600 paintings, sculptures, lithographs, photographs and other works, including those by Argentine artists Antonio Berni, Alberto Bruzzone, Prilidiano Pueyrredón, Luis Seoane, Raúl Soldi, and Juan Carlos Castagnino, for whom the museum was renamed in 1982, and of whom the museum houses 138 works.
