Eremo di San Colombano monastery is notable for its location in the side of a mountain. Some natural caves, halfway up the rock wall of the gorge formed by the stream of Leno Vallarsa were certainly used from 753 AD (the date inscribed on the rock) from a Monaco hermit.
According to legend, the hermit San Colombano first arrived there and killed the dragon that caused the death of children baptised in the waters of the river below Leno. More likely, the legend was born as a place from the first hermit monks from the nearby monastery of Bobbio, or the Priory of St. Columban Bardolino. Visitation to the site was prescribed during Lent.
Between the late tenth and early 11th century, records indicate the first construction of a small church dedicated to the saint at the opening of the cave, under a roof of natural rock. The first documentary evidence of the presence of the Hermitage and the church are one of 1319, relating to a bequest made to the Church of St. Columba on the part of Count William of Castelbarco of the House of Lords of Lizzana and Rovereto, and the other, 1470, is still preserved in Lizzana, attesting to the faith of the inhabitants of the place with celebrations and processions to the Irish saint to avert the long drought.
The hermitage of the hermit's cave was used by monks, hermits, who were its guardians, until 1782 when the practice of the hermitage was abolished. Since then the place of worship was later cared for by the inhabitants of the valley.
The province of Trent in 1996 restored the church, and the opening to the public is maintained by a group of volunteers gathered in the Committee Friends of St. Columban.
The hermitage is accessed by a staircase of 102 steps carved into rock. Frescoes depict the fight between St. Columba and a dragon (an allegory of the struggle between good and evil), as well as the representation of Paradise, located in the cave. Another fresco with 'Madonna and Saints' is the fifteenth-century altar of the church and keeps recordings with prayers and candles dated between 1505 and 1782, witnessed the pilgrimage to the shrine.
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.
