The beginnings of Maria Weißenstein go back to 1553 when Holy Mary appeared to the miner Leonhard Weißensteiner. He built a chapel which soon became a place of pilgrimage. The first Baroque church was built in 1673 and renotaved 1719-1722. The three towers were demolished in the late 1700s when the monastery was dissolved. The reconstruction began in 1800.
In August, 1885, the image of the grieving Madonna, which Leonhard Weissensteiner had kept in the chapel, was crowned again by Giovanni Giacomo della Bona, Bishop of Trient, in a ceremony attended by over 130 priests and 15,000 believers. Today the friars of the Servite Order live in the monastery and take care of a hostel.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
