Gloslunde Church was built in the 13th century. Built of red brick but now whitewashed, the church consists of a Romanesque chancel and nave and a Gothic porch and sacristy. A 14th-century timber bell tower stands close to the church's northwest corner. There are two small Romanesque windows on the chancel gable, now both bricked up. The east gable is also decorated with a round-arch frieze. The original flat wooden ceiling was replaced in the Gothic period with a star-shaped vault in the chancel and two cross-vaults in the nave.
In a Neo-Gothic frame, the altarpiece contains a painting of Christ in the Garden of Gethsemane by Frederik Christian Lund in 1872. An earlier catechism altarpiece from 1581 in the Renaissance style can be seen in the porch with text from Martin Luther's catechism in its six panels. The pulpit (c. 1590), also in the Renaissance style, presents the paintings of the four Evangelists set in rural scenes with hills and hedges.
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.
