Rehna Abbey is a former Benedictine (the 13th century) and Premonstratensian nunnery (until 1552). It was founded between 1230 and 1236. In 1254 the monastery was inaugurated and this year also began the construction of the cloister between church and convent. In the 14th and 15th centuries, the monastery was one of the most important monasteries Mecklenburg. Numerous Lübeck families had their daughters educated there and funded the monastery with donations.
During the Reformation the monastery was dissolved in 1552. From 1576 to the early 18th century it belonged to Duke widows and princesses Anna Sophia of Prussia (until 1591), Sophia of Schleswig-Holstein-Gottorp (to 1634), Anna Sophie (until 1648) and Juliane Sibylla (to 1761). At the beginning of the 18th century, the remaining buildings were used as offices until 1819. After the Second World War, the abbey was used as a school until 1995.
The late Romanesque brick church have survived from the original monastery, however it was radically altered in the mid-15th century.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.
