The Algarbes Necropolis is one of the most important archaeological ensembles of the province of Cádiz dating back to the Bronze Age (end of 3rd century BCE).
It has eight artificial caves in the shape of a circular chamber with entryways on different levels and two of them, nearly identical in symmetrical disposition, flank an ample corridor carved in sandstone. The latter correspond, due to the structure, to a big threshold related to megalithic burial grounds under a covered gallery.
The ten burial tombs may be divided in two groups. Those with a vertical entry, in the fashion of wells or grain storage silos, belong to the first group; and to the second, the vaulted ones with a side access may be adscribed. The archaeological site also houses a tomb that wholly differs from the former. It is an anthropomorphic tomb possibly assigned to a children burial.
The necropolis has been excavated in its totality by Carlos Posac Mon during the years 1967 to 1972 and the findings are of great value. Among these were found lots of ceramic urns. Pieces of bronze, ebony and gold have also been documented, as well as stone utensils, carved or polished, and ornamental objects such as pendants and perforated discs made from sea shells. Several lived in caves are found in the proximity and those were inhabited until 1930 approximately. An Islamic necropolis is also nearby.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.
