The first wooden church of Kristiinankaupunki was built between 1654 and 1658 on the site where the Ulrika Eleonora Church now stands, however it burned down on 16th June 1697. The building of the Ulrika Eleonora Church, which replaced it, was completed in 1700. The church was renovated and returned to use in 1965. The wooden church is a typical seaside church complete with a votive ship hanging from the ceiling. The ship building skills are also otherwise evident in the architecture of the church, for example in the ceiling structure. Outside the church is an old graveyard where the significant families of the city are buried. This churchyard also holds the graves of warriors of Kristiinankaupunki. Only a few services are held in the church each year. Ulrika Eleonora is a popular venue for summer weddings.
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.
