The National Gallery of National Art has a collection of paintings.
Alternatively known as the Palazzo Barberini or the National Gallery of Antique Art (Galleria Nazionale d'Arte Antica) (on the Via delle Quattro Fontane), another architectural battleground for arch-rivals Borromini and Bernini, is worth a visit as much for its splendid Baroque decor as for its collection of 13th 17th-century paintings.
