Mære Church is famous for its medieval roof with heads (human, beast and mythological) projecting from the top of its walls. The stone church likely dates to between 1150 and 1200. This is suggested by stylistic dating of its dedicatory inscription as well as coins dating from the reign of King Sverre (1183-1202) found during excavations. The pagan site buried under the church may possibly be the one referred to in the Icelandic Landnámabók Chapter 297.
The floor of the church was excavated in 1969, and found to contain the remains of a pagan cult structure. The nature of that structure was not clear. Lidén felt this represented the remains of a building, but a critique by Olsenin the same work suggested this may have be been a site for pole worship. A recent review of the evidence by Walaker Norddide in 2011: concluded that this site was similar to the site in Hove (Åsen, also in Nord-Trøndelag) and was therefore likely a cult site for pole worship. Several renovations and restorations have been undertaken over the years, most recently in the 1960s.
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.
