Hollenfels Castle, with a history dating back to the 11th century, is one of the castles located close to the River Eisch in the so-called Valley of the Seven Castles in central Luxembourg. Located at the southern end of the village of Hollenfels, the castle stands high above the River Eisch. A path with steep steps and wooden bridges leads to the foot of the castle where hollows in the rock can be seen, explaining the origin of the castle's name which literally means 'hollow cliff'. Indeed, there are several tunnels running through the cliffs below the castle. Access to the castle is by means of a brick bridge over the defensive ditch.
The first mention of Hollenfels was in 1129 when Ludolf, Lord of Hollenfels, was given the water rights of the abbey of Marienthal which lies just 400 metres away. The majestic tower, 39 metres tall, with its sumptious Gothic rooms reached by means of a spiral staircase was built in 1380. At the lowest level is the oven room, next comes the servants dining room, then the Gothic Room for the lords of the castle together with a chapel, sometimes used as a bedroom, and finally the armory at the top. The rooms have impressive fireplaces, windows set back in the sturdy walls and a number of sculptures.
Until 1477, the castle belonged to the lords of Hollenfeld and Elter. It then successively became the property of Raville of Ansembourg, Greiffenklau, Raugraves of Salm, von Thinner, von Hohenstein and Brouckhoven-Hohenstein. In the 1680s, the castle was captured by the French, taken back by the Spaniards and finally recaptured by the French. The mansion on the north-eastern side of the keep was added in 1729 and was restyled with a Baroque finish in 1921. In 1929, when the castle was falling into ruin, restoration work was carried out by the Luxembourg architect J. Schoenberg. Between 1945 and 1948, the castle was used as a camp for prisoners of war. In 1948, the Luxembourg State acquired the building and created a youth hostel there.
Today the castle houses State facilities directed towards improving the education of young people. Open throughout the year, the services allow young people to experience the historic building while coming in close contact with nature. The conditions are enhanced by the nearby youth hostel.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.
