The oldest part of Halla Church is the Romanesque nave, dating from circa 1200. The tower is slightly later, while the disproportionally large choir is from the middle of the 14th century, in Gothic style and replacing an older on the same spot. Scholars have concluded that there were plans to replace the whole church with a Gothic edifice, but the builders probably ran out of funds after constructing the choir.
The exterior of the church is thus a mix of Romanesque and Gothic. A few sculpted stones decorate the Romanesque nave. They were possibly made by the sculptor Master Sigraf. Two fragmentary runestones are immured in the choir, one containing the phrase '...men from Lübeck killed...'. The choir portal is decorated with sculptured capitals.
Inside, the nave is dominated by a large painted ceiling, dating from 1697. In the middle of the painting is a depiction of the Final Judgement, and in circles in the corners Saint Peter and Saint Paul. The choir walls are furthermore decorated with frescos, quite worn. They depict apostles and a number of saints, including Saint Martin and Saint George and the Dragon. The frescos date from the 15th and 16th centuries, and some of them have been attributed to the Master of the Passion of Christ.
The church contains two medieval items of interest. It has a triumphal cross from the middle of the 15th century, probably made outside Gotland. The church also has a baptismal font made by the master sculptor Hegvald. It is considered one of the most interesting fonts on Gotland. Its reliefs depict the childhood of Christ but also other subjects.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.
