After a short bus ride from the Hofburg through the picturesque „Wienerwald“, we reach the imposing Cistercian monastery of Heiligenkreuz, which was founded in the 12th century. The monastery has housed a theological college since 1802, which has been a theological college under papal law since 2007. The first Cistercians called the monastery "Paradisum", "paradise". This basic idea is also reflected in the architecture. In the Romanesque-Gothic cloister, many hundreds of red marble columns from 1240 represent the trees of paradise, which end in the buds and tendrils of the capitals. The keystones of the mighty vaults symbolize the floral splendour of paradise. In the middle of the cloister is a lovingly tended garden. We will gain a comprehensive impression of everything from the Rococo frescoes in the sacristy to the lovely Anna Chapel. We visit the whimsical Baroque mortuary chapel, the Gothic chapter house, which is the burial place of the last Babenberg, Frederick the Quarrelsome († 1246), and the colourful glass panes from the 13th century that depict the Babenberg family. We will then travel a short distance by bus to the Mayerling hunting lodge – a place steeped in history, embedded in an impressive landscape. It was precisely where the Carmelite monastery church stands today that Crown Prince Rudolf, and his lover Mary Vetsera met their deaths on 30 January 1889. Let us immerse ourselves in the myth that tells of the drama of two young people and the consequences of a love that could not be. The bus will then take us back to the Hofburg.
