Hällestad church was built of stone in the 12th century. It was enlarged in the 15th century and the tower was erected probably in the late Middle Ages. The church was restored and enlarged in the mid-1800s.
There are mural paintings from the 1400s in the vaults, made by so-called “Vittskövle Master”. Three Viking age runestones are located to the eastern wall outside 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.
