Poseritz Brick church is built on foundations of large fieldstones. There are individual fieldstone courses in the tower. Work on the nave began between 1302 and 1325. The structure was designed as a three aisle hall structure, and this plan was followed in the first phase of construction, visible in the applied columns to the left and right of the tower entrance. Those to the east were removed in widening the triumphal arch, when a broader choir than originally planned was added, which required cuts into the east wall of the nave. The outer walls originate from the three aisle hall church. But in the second phase of construction the church was finally erected in the form of a triple-bay hall with buttresses. The choir, nave, and sacristy have cross vaulting, applied columns supported outside by abutment piers. Choir with rectangular termination built shortly afterwards in the 14th century. The sacristy was added afterwards in about 1400 to the north between the choir and the east wall of the nave. Massive west tower dating from later than 1450 using existing denticulation, a polygonal spire being added in 1580. The west portal with its segmental arch has an old, nailed diamond pattern door. The interior is plastered in white.
Oldest furnishings and accessories are the 14th century limestone font and Gothic crucifix over the south portal from about 1400. Other furnishings include offertory box from the 15th century, bell from about 1500, large triumphal cross ensemble with 16th century cross, Mary and John from the 15th century, two wooden patron chairs from 1598 and 1600, memorial tablet from 1600, late Baroque carved altar from 1703, confessional from 1747 and Rococo pulpit by Jakob Freese, Stralsund, from 1755.

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.
