Glasgow Cathedral is the oldest cathedral on mainland Scotland and is the oldest building in Glasgow. The history of the cathedral is linked with that of the city, and is allegedly located where the patron saint of Glasgow, Saint Mungo, built his church. The tomb of the saint is in the lower crypt. Walter Scott's novel Rob Roy gives an account of the kirk.
Built before the Reformation from the late 12th century onwards and serving as the seat of the Bishop and later the Archbishop of Glasgow, the building is a superb example of Scottish Gothic architecture. It is also one of the few Scottish medieval churches (and the only medieval cathedral on the Scottish mainland) to have survived the Reformation not unroofed.
James IV ratified the treaty of Perpetual Peace with England at the high altar on 10 December 1502. The cathedral and the nearby castle played a part in the battles of Glasgow in 1544 and 1560. Twenty years after the Reformation, on 22 April 1581 James VI granted the income from a number of lands to Glasgow town for the kirk's upkeep. He traced the ownership of these lands to money left by Archbishop Gavin Dunbar as a legacy for repairing the cathedral. The town council agreed on 27 February 1583 to take responsibility for repairing the kirk, while recording they had no obligation to do so. The church survives because of this resolution. Inside, the rood screen is also a very rare survivor in Scottish churches.
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.
