The medieval church of Solna is a so-called round church. The oldest part of the church, the roundhouse, originates from the late 12th century, and was especially built for defense purposes. Attached to this round center is a weaponhouse (south), a rectangular choir to the east, and a rectangular nave to the west. North of the choir is the sacristy, and to the east an octagonal grave choir. There is a second grave choir on the south side of the nave. The roundhouse (central tower) is covered by a tall cupola, which dominates the appearance of the church. The choir was added in the 13th century. The oldest part of the nave is from the 14th century, and was extended during the 15th century, when the weaponhouse and sacristy were built.
The church achieved large parts of its interior under the patronage of Magnus Gabriel de la Gardie. In 1674 the western portal was added, a sculptured portal originally constructed for Karlbergs slott in 1637, and moved to Solna church in 1674. In 1708 Queen Ulrika Eleonora commissioned a grave choir dedicated to count Tomas Polus. The roof was destroyed in a fire in 1723, and the current cupola was built after this incident. The Lange grave choir was constructed in the 1780s. In 1883 the church was given a roof of copper plates. A major restoration took place in 1928 under supervision of architect Erik Fant, when the church's medieval paintings were recovered. The medieval murals from ca. 1440 are attributed to Albertus Pictor.
The choir is dominated by the altar centre-piece, sculpted in wood in 1666 by Hans Jerling. The centre-piece frames two oil paintings with biblical motifs, and is crowned by a wood-sculptured Madonna from the late 16th century, while the altar is made of brick and covered by a limestone plate.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.
