Veng Abbey was one of Denmark's earliest Benedictine monasteries, established in the late 1060s, with connections to the royal forebears of King Valdemar I. By the 1160s the abbey had fallen into a severe decline: the original endowments failed to sustain it, and it had gained a reputation for being 'unruly'. Eventually Abbot Jens was brought before a church tribunal and forced to give up his office on the grounds of immorality and theft of the harvest. Three recalcitrant monks were all that remained at Veng, and Svend, Bishop of Aarhus, received permission from Pope Alexander III to close the abbey.
Just a year later Bishop Svend granted occupation of the empty premises to the Cistercian monks from Sminge Abbey, originally from Vitskøl Abbey, who were dissatisfied with the infertility of the soil at Sminge. They settled at Veng Abbey in 1166. It looked like a very good location for the Cistercians, but they had not reckoned with Lady Margrethe.
Lady Margrethe was the widow of a local nobleman. She had petitioned Bishop Svend to convert Veng Abbey into a nunnery with herself as the abbess, a position which would bring with it a guaranteed annual income. When the Cistercians were confirmed at Veng, she did everything she could to make life miserable for them. She had her servants occupy the rent-producing farms that had belonged to Veng, and was accused of ordering one of her servants to steal the vestments from the church so that mass could not be said. Without income, the Cistercians had no choice but to leave, and in 1168 moved to another site on Kalvø Island in Skanderborg Lake.
On Kalvø, as previously at Sminge, the soil proved useless for farming and in 1172 the monks moved yet again to found Øm Abbey, where at last they were able to develop a permanent site, so successfully that Øm Abbey soon overshadowed the earlier existence of Veng Abbey. The few archival letters regarding Veng were transferred to Øm Abbey and the little information now available about Veng Abbey is due to their preservation there.
The abbey church, dedicated to the Holy Trinity, was constructed some time after 1100, probably as a replacement for an earlier wooden structure. It was built of limestone blocks, as were many early Danish monasteries, in the Romanesque style. It had a flat timber roof, a single nave, a choir, and an apse with two transepts, each with its own apse. The outside of the church retains several carved stones and other decorations from the original building.
The exact layout of the monastery complex has not been determined, but it is thought to have had at least two ranges, a dormitory, and a refectory attached to the church. Excavations in 1984 to determine the layout were unsuccessful.
The abbey church became the parish church of Veng, while the conventual buildings were converted for use as a farm. Even before the Danish Reformation there were no remains of Veng Abbey except for the church.
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.
