Portugal's premier collection of old masters is housed in a 17th-century palace high on a cliff overlooking the River Tagus. It includes sections on Portuguese painting from the 15th to the 19th centuries, a huge decorative arts collection, and a selection of European art dating back to the Flemish Primitives and the early years of the Italian Renaissance. Amongst it all are some world-class masterpieces: Hieronymus Bosch's nightmarish vision of "The Temptation of St. Anthony"; "The Saint Vincent Panels," Nuno Gonçalves' extraordinary depiction of Discovery-era Portuguese society; Francisco de Zurbarán's 12 larger-than-life portraits of the apostles; a wickedly seductive Salome by Lucas Cranach; and nanban screens from Japan showing the arrival of early Portuguese traders. In recent years, the MNAA has hosted major exhibitions of works from partner museums, including 18th-century treasures from the royal House of Savoy sent by the Palazzo Madama in Turin. Beyond the art, the place affectionately known as the "Museum of Green Windows" is a favorite escape from the bustle of the city, especially on Sunday mornings when entry is free and locals settle in with coffee, pastries, and newspapers to while away time in the leafy garden and to enjoy the view across the wide expanse of water below.
