The Mezquita was built from a visigothic basilica from the 5th century, reusing its materials, and is one of the few surviving Spanish rural mosques.
It is an oddly-shaped building, made of brick and stone in a trapezoid shape, probably because of the hilly terrain. The oration room has 5 naves, whose arches, like in the Mezquita in Cordoba, are perpendicular to Qibla. The central nave is wider than the 2 nearby, which are in turn wider than the 2 outer naves. The Mihrab has lost its paint, and looks quite archaic; only the brick and stone is visible. In the oration room, 16 undated tombs were found.
When Spain became Christian, many changes were made, including the addition of a central axis in accordance with the new religion. The old door and the North flank were also reconstructed. Despite these changes, the whole building still retains a rustic charm.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.
