Gewerkenegg Castle dominates the Idrija city. It was erected at the beginning of the 16th century to serve as the administrative headquarters and warehouse of the Idrija mine, then the second largest mercury mine in the world. The now beautifully restored Renaissance complex experienced a Baroque renovation in the middle of the 18th century when the inner arcaded courtyard was created and painted with attractive decorative frescoes.
The castle now houses the Idrija Museum, whose central exhibit-Five Centuries of Mercury Mining and the Town of Idrija-offers a survey of the half-millennium history of the oldest mining town in Slovenia. It also offers an exhibit of Idrija lace, a replica of a room in an Idrija miner's home, peasant frescoes, memorial rooms of the writer France Bevk and the politician Aleš Bebler, and a collection of paintings donated by the gallery owner Valentina Orsini Mazza. The castle also provides rooms and a concert hall for the Idrija Music School. Throughout the year, the museum organizes various events, presentations, and receptions in the castle hall. The Museum Evenings lecture series is especially popular. In summer, the Castle Evenings program of cultural events, mostly concerts, moves into the castle courtyard.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.
