Heiligenkreuz Abbey sits beautifully in the Vienna Woods and stands as the world's oldest continuously occupied Cistercian monastery, dating back to 1133. Founded by Margrave St. Leopold III of Austria at his son Otto's request, the monastery welcomed its first twelve monks from Morimond in Burgundy, led by Abbot Gottschalk. The abbey was consecrated on September 11, 1133, taking its name "Heiligenkreuz" (Holy Cross) to reflect the monks' devotion to the Cross.
The monastery's rich history includes receiving a precious relic of the True Cross in 1188 from Leopold V of Austria—a gift originally from Baldwin IV, King of Jerusalem. This sacred relic remains on display in the Holy Cross chapel today. With generous support from the founding Babenberg dynasty, Heiligenkreuz flourished and went on to establish numerous daughter monasteries throughout the region.
Adding to its architectural splendor, the abbey's large inner courtyard features an impressive baroque masterpiece: the Trinity Column. This majestic monument was designed by Italian-Austrian sculptor Giovanni Giuliani and completed in 1739. Standing prominently in the monastery's central courtyard, the Trinity Column represents a beautiful example of Austrian baroque art and serves as a lasting symbol of the abbey's spiritual mission and artistic heritage.
