Sakshaug Old Church is one of the oldest churches in Trøndelag, dating back to about 1150. The church was consecrated by Archbishop Eysteinn Erlendsson in 1184 and was decommissioned in 1871 when the new Sakshaug Church was consecrated. The ownership of the church was transferred to the Society for the Preservation of Ancient Norwegian Monuments in 1873 and was renovated from 1910 to 1958 after having been without a roof and the interior since 1873.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.
