St. Lambrecht's Abbey was founded in 1076 by Count Markward of Eppenstein; it was dissolved from 1786 to 1805. In 1938, the building was seized by the National Socialists. From 1942 to 1945, it was used as an external storage facility of the Mauthausen-Gusen concentration camp. The monks returned in 1946.
Locally the two churches within the monastic grounds are called the Grosskirche ('big church') and the Kleinkirche ('little church'). During restoration work of the Grosskirche in the early 1970s extraordinary frescoes dating from the latter half of the 15th century were discovered on the north wall. These show the throne of Solomon.
On the lowest level is depicted the Old Testament Judgment of Solomon, above this the Virgin Mary with the baby Jesus, and above all else Jesus Christ: 'the Word of God made Flesh'. Other frescoes dating from the 14th century depict Saint Christopher and Saint Agnes. Formerly in the monastery there was also a votive altarpiece from which the Master of the Saint Lambrecht Votive Altarpiece received his name; this is now in the Alte Galerie in Graz.
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.
