Glasgow Cathedral, also called the High Kirk of Glasgow or St Kentigern's or St Mungo's Cathedral, is today a gathering of the Church of Scotland 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.

Technically, the building is no longer a cathedral, since it has not been the seat of a bishop since 1690. However, like many other pre-Reformation cathedrals in Scotland, it is still a place of active Christian worship, hosting a Church of Scotland congregation. The current minister (since 15 February 2007) is the Rev Laurence A. B. Whitley, PhD,(Retired 2017) who was previously minister at Montrose Old and St Andrew's Parish Church. The previous minister was the Very Rev William Morris, who was minister from 1967 until retiring in November 2005. The building itself is in the ownership of the Crown, is maintained by Historic Scotland, and is a popular destination for tourists.

This is the second cache that we placed on our New Year's Trip across Scotland. Cathedral exterior is very nice, especially in the evening. To find the cache you will need to check information board for St Mungo Museum of Religious Life and Art.
