The construction of defensive tower, the oldest part of Hulterstad Church, was completed around the year 1200. There are also some remains of older building from the early 1100’s below the ground. In 1803 the church was reconstructed to the present, single-nave and rectangular shape.
The interior originates from several centuries. Oldest artefacts are the baptismal font and the painted consecration cross from Middle Ages. Mural paintings in arches were painted in the 1600s. The large bell was made in 1631 by Jurgen Putensen. The organs date from 1867, designed by L. Hedin. In 1676 the royal warship wrecked outside Hulterstad and a most of the crew were buried in the cemetery.
There is a small museum in one of the tower's floors including some runestones. Some stones have been found under the tower's ground floor.
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.
