This sprawling complex houses the National Library, National Technical Library, and no fewer than four Baroque chapels. The Mirror Chapel, dating back to around 1724, has dark decor in marble and stucco, with gilded harp and trumpet playing cherubs sailing over one of the two 18th-century organs. Concerts are held nearly every day here at 5p and 8p. Baroque music, naturally, features strongly. The ever-popular Bohemia Saxophone Quartet performs regularly, otherwise, it's standard chamber ensembles. The organs also get frequent workouts.
