St Moluag's church (Teampall Mholuaidh in Scottish Gaelic) was built in the 13th century. The church has a basic T shaped structure, with two small chapels on either side of the main body of the church. The southern chapel can only be accessed from outside. There is a lot of speculation about the ancient origins of this place of worship; one tradition tells that St. Ronan founded the church, before retiring to the Isle of Rona (in legend travelling on the back of a whale).
The church is now in use as a Scottish Episcopal Church. There are ruins of another temple 'Teampall Ronaidh' about 500m north east of Teampall Mholuaidh and remains of another temple 'Teampall Pheadair' are about 2km south west of Teampall Mholuaidh beside the old graveyard near the village of Swainbost.
The church is dedicated to the shadowy figure of St Moluag. It has been suggested that the church was built by the son of a Scandinavian king, who had converted to Christianity.
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.
