Tingvoll Church is one of the few remaining old stone churches that was built in Norway. There is some uncertainty as to when it was actually constructed, but records indicate it was between 1150 and 1200. The church is 32 metres long and the steeple and spire (added in 1787) is 36 metres tall. The 1.8-metre thick walls have corridors inside, both on the south side and on the north side. The corridors lead to steep stairs up to the crown of the wall under the rafters and then down again with the same steep pitch. It is a mystery why they were constructed. So also a balcony outside under the gable, located above the chancel. The church is richly decorated. From the painted walls in the weaponhouse, the whitewash paintings inside the nave, to the arc ceiling in the chancel which is adorned with stars and 'half' moons. In the chancel wall, behind the top of the altarpiece, there is a marble rock with runic inscriptions. This inscription contains a prayer and also what is believed to be the name of the constructor - Gunnar. In 1928-1929 the church underwent some restoration work.
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.
