The first church in Bro was built during the 12th century in Romanescue style. The next church was completed in 1236 and it represented the Gothic style. In the reconstruction around 1300 the nave was demolished and replaced with the present one. In the Middle Ages Bro church was a destination for pilgrimages, because very important relic, an “original” piece of Jesus Christ’s cross was kept there. The pilgrimage tradition has been continued also after Reformation.
The baptismal font and Holy Rood date from the 13th century, wall paintings from 14th -15th and 18th centuries. Partly medieval choir stall, reredos was made in 1688 and pulpit 1723.
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.
