St Moluag's church (Teampall Mholuaidh in Scottish Gaelic) was built in the 13th century. The church has a basic T shaped structure, with two small chapels on either side of the main body of the church. The southern chapel can only be accessed from outside. There is a lot of speculation about the ancient origins of this place of worship; one tradition tells that St. Ronan founded the church, before retiring to the Isle of Rona (in legend travelling on the back of a whale).
The church is now in use as a Scottish Episcopal Church. There are ruins of another temple 'Teampall Ronaidh' about 500m north east of Teampall Mholuaidh and remains of another temple 'Teampall Pheadair' are about 2km south west of Teampall Mholuaidh beside the old graveyard near the village of Swainbost.
The church is dedicated to the shadowy figure of St Moluag. It has been suggested that the church was built by the son of a Scandinavian king, who had converted to Christianity.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.
