The oldest part of the Alskog church is the nave, dating from the first quarter of the 13th century. It displays an unusual southern portal, decorated with sculptures. Inside, the nave is divided in two parts by two central columns and has a vaulted ceiling. The tower is somewhat later but also from the early 13th century. Its portal show similarities with the tower portal of Visby Cathedral. The much larger choir and vestry were added circa 1300. The ambition was probably to rebuild the whole church into a larger, Gothic church, but for some reason only the eastern part of the church was rebuilt.
Few alterations have been made since the Middle Ages. During the 19th century, some windows were added and new pews installed. The church underwent a renovation in 1964-1965.
Of the furnishings, the triumphal cross, dating from circa 1200 is perhaps the most noteworthy, together with the richly carved baptismal font, complete with substantial traces of original colour, from the same time. A few separate medieval sculptures also survive, originally part of a 14th-century retable. The church windows have several preserved stained glass panes from around 1300, probably when the choir was built. They depict scenes from the life of Jesus. From the time after the reformation, the pulpit deserves mention. It was made in 1586 and is the oldest pulpit on Gotland. The church also has a pair of embroidered bags for collection of alms made in Istanbul in 1775. They were brought to the church by the priest at the Swedish legation in the city, who was the son of a pastor in Alskog Church.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.
