The Museo Municipal de Bellas Artes Juan B. Castagnino (Avenida Pellegrini 2202, tel. 0341/480-2542, www.museocastagnino.org.ar , 2–8 p.m. Mon.–Wed. and Fri., 1–7 p.m. weekends, US$1) is the top fine arts museum. Housed in a spacious building dating from 1937, it boasts a diverse collection starting with a small assortment of European masters through 19th-century and later landscapes (both European and South American).
Its strength, though, is modern Argentine art both figurative and abstract, much of it by Rosarinos. Among the prominent artists on display are Prilidiano Pueyrredón, Benito Quinquela Martín, Antonio Berni, and Eduardo Schiavoni.
