Lunenburg Castle was first mentioned in 1339 and it was probably owned by the Van Zijl family. The tower house itself was first mentioned in 1400. In 1402 it was given as a fief to Ghijsbrecht van Lockhorst.
In 1680 Lunenburg Castle was enlarged with residential wings and stables which were built against the medieval tower house. In 1860 the owner at that time, a member of the Van Swinderen family, rebuilt the castle. The 17th century additions were torn down and that almost the entire moat was filled in. The medieval tower house was then incorporated in a new large mansion which rendered the tower almost invisible. After this the castle was rented out and sold several times.
Between 1925 and 1931 the castle was owned by Mr. Ernest Reinier van Eibergen Santhagens who provided the castle with modern comfort.
On 13 May 1940 Lunenburg Castle was searched by German troops for hidden arms and ammunition, causing much damage in the process. In 1944 the Germans had parked military vehicles under the large trees on the grounds of Lunenburg Castle. This led to a useless bombardement of the castle by Allied forces, because the vehicles had already been removed, which left the castle as an uninhabitable ruin.
Between 1968 and 1970 Lunenburg Castle was rebuilt after its appearance before 1800. This led to the situation we see today. At present the castle is owned by the Fentener van Vlissingen family. The present tower is 15,5 meters high, is almost square with 8,4 by 9,3 meters and has a wall thickness of 1,2 meters.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.
