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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
