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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
