Fundación Juan March
Established by Spanish financier and philanthropist Juan March in 1955, this namesake foundation organizes free classical concerts in a multistory cultural center in the Salamanca neighborhood. Held in a 300-seat theater, the concerts feature chamber orchestras, choirs, and soloists. The performances take place at noon on most Mondays and Saturdays, as well as on Wednesday evenings when the national radio broadcasts the music. The foundation center also contains a permanent exhibit of contemporary Spanish artwork and a library of 4,000 books relating to music and theater from the 19th century to present day.
