Brechin Cathedral dates from the 13th century. Immediately adjoining the cathedral to the southwest stands the Round Tower, built about 1000 A.D.
The western gable with its flamboyant window, Gothicdoor and massive square tower, parts of the (much truncated) choir, and the nave pillars and clerestory are all that is left of the original edifice. The modern stained glass in the chancel is reckoned amongst the finest in Scotland.
The quality of the masonry is superior to all but a very few of the Irish examples. The narrow single doorway, raised some feet above ground level in a manner common in these buildings, is also exceptionally fine. The door-surround is enriched with two bands of pellets, and the monolithic arch has a well-preserved representation of the Crucifixion. The slightly splayed sides of the doorway (also monolithic) have relief sculptures of ecclesiastics, one of them holding a crosier, the other a Tau-shaped staff.
Two monuments preserved within the cathedral, the so-called 'Brechin hogback', and a cross-slab, 'St. Mary's Stone' are further rare and important examples of Scottish 11th century stone sculpture. The hogback combines Celtic and Scandinavian motifs, and is the most complex known stone sculpture in the Ringerike style in Scotland. The inscribed St Mary's Stone has a circular border round the central motif of the Virgin and Child which echoes that on the Round Tower.
As a congregation of the Church of Scotland, which is Presbyterian, the church is not technically a cathedral, in spite of its name.
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.
