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.
The National Gallery of National Art has a collection of paintings.
