Differdange Castle was built in 1577 although an earlier fortified castle of Differdange dates from around 1310. The first lord of the castle was Wilhelm, brother of the Lord of Soleuvre, who is mentioned in documents from 1310 when he owned a fortified castle. However, the lords of Differdange lasted only until the death of Wilhelm's grandson around the year 1400. When Soleuvre Castle burnt down in 1552, the owner Anna von Insenburg decided not to repair it but to build a Renaissance-style residential castle in Differdange serving both Soleuvre and Differdange. At the beginning of the 20th century, the castle came into the hands of the local steel industry, now Arcelor Mittal who used it as a hotel and a restaurant for its staff.
Differdange Castle is probably the earliest example in Luxembourg of a château built entirely in the Renaissance style. It was originally intended both as a residence and a fortification with a moat and draw-bridge (now both removed) as well as loop-holes. It is constructed fully in accordance with the principles of Renaissance architecture, especially the use of the square both for the courtyard and the outer walls of the three buildings which surround it. The rectangular cross-framed windows are typlical of the period. The octagonal towers which are slightly higher than the central building provide balance between the horizontal and vertical dimensions.
Since 1997, the castle has been let to Miami University for use as its Miami University Dolibois European Center.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.
