The Baroque Mariatrost Basilica is one of the most famous pilgrimage sites of Styria in Austria. The pilgrimage church stands prominently on top of the Purberg hill in the northeast of Graz. It can be reached using the 200 or more steps of the Angelus stair. The basilica is classified as a Baroque building. Two front towers and a dome, visible from a great distance, are the characteristic attributes of the church, which is enclosed by two projecting wings of a former monastery once occupied by the Pauline Fathers (1708–86) and later by the Franciscans (1842–1996).
The building was begun in 1714 by Andreas Stengg and his son Johann Georg Stengg and finished in 1724. The pulpit by Veit Königer (1730/1731) is the masterpiece of the furnishings. The frescoes on the ceiling by Lukas von Schram and Johann Baptist Scheidt are of particular importance.
The main altar includes a statue of the Madonna originally created in the Gothic period around 1465, but altered to the Baroque style in 1695 by Bernhard Echter.
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.
