McNay Art Museum, Modern art museum in Alamo Heights, United States.

The McNay Art Museum occupies Marion Koogler McNay's 24-room Spanish Colonial Revival mansion, built in 1927 by Atlee Ayres and his son Robert M. Ayres, on 23 acres with fountains, broad lawns, a Japanese-inspired garden and fishpond. The 2008 Jane and Arthur Stieren Center for Exhibitions, a 45,000-square-foot building by Jean-Paul Viguier, adjoins the house with light-filled galleries for special exhibitions, sculpture and works on paper.

Marion Koogler McNay, a painter and art teacher who inherited an oil fortune, built the 24-room Spanish Colonial Revival house in 1927 with architects Atlee Ayres and his son Robert M. Ayres. When she died, she left the house, most of her fortune and her art collection to the City of San Antonio, and the McNay Art Museum opened in 1954 as Texas's first modern art museum. The Jane and Arthur Stieren Center for Exhibitions, designed by Jean-Paul Viguier, was added in 2008.

The museum's name honors Marion Koogler McNay, a painter and art teacher who built the 1927 Spanish Colonial Revival mansion that now holds the collection. The Tobin Collection of Theatre Arts, among the leading stage-design holdings in the U.S., and a 30,000-volume research library are also part of the institution.

The museum occupies a 23-acre campus in Alamo Heights, with the 1927 mansion at its centre and the 2008 Stieren Center adjoining it; the Japanese-inspired garden and fishpond lie on the landscaped grounds. Allow time to move between the historic house galleries and the newer exhibition wing. The research library holds over 30,000 volumes.

The Tobin Collection of Theatre Arts, one of the leading collections of its kind in the United States, is housed here alongside the art galleries. It covers stage design, costume sketches and theatrical garments, and the museum's research library holds over 30,000 volumes for visitors who want to dig into the theatre material.
