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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
