Dolmen de Dombate is arguably the one of the most valuable megaliths located in Spain. Not only due to the relative good conservation of the monument, but also for several peculiarities that make it unique. The monument is actually two Tombs constructed in two different time frames, one over the other. The dolmen (dated 3900 BC) is composed of a 24m diameter, 1,8m high barrow which does not seem to have totally covered the actual chamber. The later is a poligonal chamber composed of seven orthostats (the bigger one at the back of the monument is 4,7x3m) covered by a massive capstone. This chamber was accessed by a three segment - 4m long - corridor made of six orthostats of decreasing heights. The corridor, covered by a capstone and probably by the barrow, is oriented to the East.
Inside the megalith, several petroglyphs have been found, but what makes this Dolmen unique in Spain is the discovery of several paintings in both the chamber and the access corridor. These pictures are Zig-Zag motives in reddish colour with black dots over a whitish base. Objects encountered inside the tomb reveal different periods of usage, and range from early neolithic silex blades to pre-beaker pottery. All in all the Dolmen was used from its creation (3900 BC) to 2700BC when a final lith was installed blocking all access.Other objects dating from 2700BC to contemporary times have been found since the first re-opening of the megalith by Beaker Culture gravediggers.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.
