Venø Church's age is difficult to date but it was probably built around the time of the Reformation (1536), making it the oldest building on the island. According to tradition, it is the smallest church in Denmark measuring only 9.8 by 4.2 meters. The low ceiling and the limited seating capacity (only about 50 places) reinforce this impression. The church is built of fieldstone while brick has been used for the corners and later extensions. There is no tower as the church bell is inside the gable at the west end of 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.
