The Kirna estate was given as a gift to the von Fersen family in 1614 and remained in the ownership for over a hundred years. After 1787, it belonged to various Baltic German and Russian families from the nobility. After 1919 it was used as a school up until World War II. During the Soviet occupation of Estonia, the manor housed the offices of a collective farm. Today it stands in private ownership and is used for it's energetically propitious place as spa.
The building received its present appearance during a neoclassical reconstruction of an earlier building around 1820. The hall and other ceremonial rooms on the main floor was at that time also decorated with typical stucco ornaments. Some later additions were in a neo-Gothic style. The family cemetery of the von Osten-Sacken family together with the ruins of a funeral chapel reminding one of an antique temple are located near the centre of the estate.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.
