Nothing remains of the preceding structure of Bobbin Church (mentioned in 1250, originally owned by the Bergen monastery). The present church is an imposing, fieldstone structure with shaped brick elements plastered so as to leave the underlying surface visible. Brick is used for the corners of the building, gables, buttresses, vaults, and all ornamentation. The nave, choir, and sacristy were built in about 1400. It has a rectangular nave with a flat wooden ceiling, and a retracted, rib-vaulted choir. The two square choir bays have been repeated in enlarged form in the nave. The interior is whitewashed and in 1955 was painted in simple form. Floors are of limestone tiles. The choir is a step higher than the nave. The windows were enlarged, probably in the Middle Ages. The “Likhus” on the south side of the choir was built in the 17th century, and was extended in the 17th century to provide access to the patron’s box. The west tower was built in about 1500 of brick with a sprinkling of fieldstone (the upper part still later). Steep pavilion roof with a weathervane from 1657.
Oldest furnishings and accessories: Gotland limestone font from about 1300 (presumably from the preceding church). Cuppa wall decorated with twelve blind ogee-arches. Worth noting: the iron-grilled aumbry inserted in the south wall of the sacristy (from about 1400), decorated with Gothic tempera painting and carving, beside the altar sacrament house with iron-studded wooden door under a canopy and quatrefoil. Other furnishings: pulpit from 1622 (late Renaissance), high altar with choir screen (1668) and patron's box, confessional from 1775 (workshop of Michael Müller, Stralsund), portraits, sepulchral slabs. The churchyard is worth a visit.
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.
