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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
