With a collection spanning three centuries, starting in the era following Charles IV's golden reign, this little gallery perhaps tries to do too much. It also seems overlooked, maybe because it stands next to so many better collections of the National Gallery at the castle complex.
Nonetheless, some florid pieces - Bartholomeus Spranger's Allegory of the Turkish War, Lucas Kranach's portrait of Sts Catharine and Barbara from the altar of St Vitus's Cathedral - do offer a glimpse of the splendour that once filled the environs around what is, today, a tidy and all-too-well-run tourist attraction. The gallery also includes works by Hans von Aachen, Veronese and lesser-known masters. And though there's no hope of ever piecing together Emperor Rudolph II's magnificent original collection, which has been scattered to the winds, the castle shows off a handful of works from the original cache.
