Castillo de Moguer was renovated and enlarged in the 14th century. The oldest record document of castle dates from 1362, but it probably existed already in the Moorish age.
The castle was built of mud-based mortar gravel, clay and lime. It is of an imperfect square plan 44 by 45 metres in size, with four towers at the corners. A moat surrounded the castle, as evidenced by written records, but is not currently visible. Access to the castle was across the northwest side, now Santo Domingo Street, via a ramp. Each tower measures 9 by 9 metres and contains two chambers with a covered brick dome. The four towers were topped by battlements. A cellar dating to the 18th century, measures 22 by 10.5 metres and serves as the headquarters of the Tourist Office.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.
