The 18th-century Chapel of the Holy Cross houses the St Vitus Treasury, a spectacular collection of ecclesiastical bling. Gold and silver reliquaries crusted in diamonds, emeralds and rubies contain saintly relics ranging from fragments of the True Cross to the withered hand of a Holy Innocent.
The oldest items include a reliquary arm of St Vitus dating from the early 10th century, while the most impressive treasures include a gold coronation cross of Charles IV (1370) and a diamond-studded baroque monstrance of 1708.
