Maria Rickenbach Monastery was initially established after a 1528 painting of the Blessed Mother was placed in a hollow maple tree on that site. Subsequently, unable to remove the painting, which came to be considered miraculous, the church and monastery were established around the tree, which is now enclosed by a shrine.
In 1857, a small group of women who wanted to follow a monastic way of life acquired the monastery. There they established the practice of Perpetual Adoration as a part of their life. The monastery is often associated with Engelberg Abbey, under the guidance of which they were established and later became formally incorporated into the Benedictine Order.
It is accessible to the public only by cable car from Niederrickenbach Station on the Luzern–Stans–Engelberg railway line.
References: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.
