One of the newer permanent exhibitions at Prague Castle, the Treasury is the largest in the country and one of the most significant church treasuries in Central Europe. Highlights include a gold coronation cross crafted during the time of Charles IV; reliquary busts of the Saints Vitus, Wenceslas and Adalbert, who are not only the cathedral’s principal patron saints but also the historical protectors of the Kingdom of Bohemia; a diamond-studded monstrance from the baroque era and probably the most bizarre item, a relic of the arm of Saint Vitus, acquired by Prince Wenceslas in 929 from Henry I, Duke of Saxony. The exhibition is a fascinating journey through the history of spiritual wealth amassed in the region.
