Tingelstad Old Church is a Romanesque stone church in Gran. Dendrochronological dating shows that parts of the timber within the church were felled between 1219-1220. The original name for this church was 'St. Petri Church', although presently it is called Tingelstad old church (Tingelstad gamle kirke) as it was replaced by a new church in 1866.
The congregation also had a stave church (Grindaker stave church), but this was demolished in 1866, again because it was too small.
The spire on the wooden belfry bears a copy of a 12th-century weather vane. The original vane is held in the Museum of Cultural History in Oslo. It is believed that it was once fitted to the bow of a warship. Although the church contains a few other original, medieval features such as a wooden crucifix and a stone altar, it is best known for its intact interior from the 16th and 17th centuries. The pulpit is from 1579 and is one of Norway's oldest. An altar frontal from 1699 can also be found in the church. A unique mural from 1632 depicting the Dano-Norwegian coat of arms, has been partially revealed on the interior North wall.
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.
