The St Serf's Inch Priory was a community of Augustinian canons based, initially at least, on St Serf's Inch in Loch Leven. It was founded from St Andrews Cathedral Priory at the instigation of King David I of Scotland in 1150. There was a Scottish Céli Dé (or Culdee) establishment there in the first half of the 12th century, allegedly found by Bruide, son of Dargart, King of the Picts (696–706). Presumably it was dedicated to St Serb (Serf or Servanus), and there are indications that the Scottish establishment had a large collection of writings, mostly lost now or translated into Latin.
When the Augustinian priory was founded in 1150, the Scottish monks were absorbed into the established and those who refused to join were to be expelled. In the 15th century the priory begins to be referred to as 'Portmoak', perhaps indicating that the canons had partially relocated there from the island. Following more than four centuries of Augustinian monastic life and the resignation of the last prior, the Protestant king, James VI of Scotland, granted the priory to St Leonard's College, St Andrews. At some point in time, the structure was converted into a fishing hut or bothy.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.
