The western part of the nave and the church tower are the oldest parts of the asymmetrical Vallstena church. They date from the early 13th century. A new chancel arch was built at the middle of the same century, and around circa 1300 the new choir was built. Reconstruction of the nave also started around this time; the original plan seems to have been to replace the entire nave with a new, larger nave but for some reason the work came to a halt. Similar, half-rebuilt churches are relatively common on Gotland. The sacristy was also built at this time. The interior of the church was decorated with church frescos during the 15th century.
The church and its cemetery is surrounded by a low wall, with three lychgates. The oldest of these dates from the 13th century and display some original sculptured details.
The baptismal font is the oldest fitting of the church, dating from the middle of the 13th century. The altarpiece dates from the 14th century and was acquired when the new choir was inaugurated. From the same century dates a crucifix, as well as a richly decorated chest for donations for the poor. From the 14th century are also to tombstones on either side of the altar, carrying inscriptions in both Latin and Old Gutnish; the latter in runes. A few 14th century wooden statues depicting saints originally from Vallstena Church are today housed in Gotland Museum in Visby.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.
