The Haga dolmen (Hagadösen) is a megalithic dolmen, dating from the Neolithic era. It is located on the island of Orust in Bohuslän, about one kilometre to the east of Tegneby Church. Not far from the dolmen is a second, smaller one, and about 250 metres west of it a large passage grave can be found.
The grave consists of four raised stone slabs, with a fifth slab placed as a roof, with an additional threshold stone by the entry and a stepping stone. It is surrounded by a small mound of earth, and some barely visible edge stones. While small in size, the dolmen has the province's largest inside chamber. It has a rough dating of about 3400 BCE.
Several artefacts were found during an archaeological excavation in 1915 by Arvid Enqvist, among them an amber necklace, a stone axe, a flint knife, and some slate jewellery. These finds were dated to the late Neolithic. No grave finds from the dolmen's primary period, the early Neolithic, have been discovered. The neighbouring dolmen was also excavated at this time.
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.
