The Mosque of Cristo de la Luz is a former mosque in Toledo. It is the only one of ten that once existed in the city that remains largely as it was in the Moorish period. Legend has it that a shaft of light guided the king to a figurine of the crucified Christ that had been hidden for centuries. He left his shield there with the inscription, 'This is the shield which the King Alfonso VI left in this chapel when he conquered Toledo, and the first mass was held here'.
In 1186, Alfonso VIII gave the building to the Knights of the Order of St John, who established it as the Chapel of the Holy Cross (Ermita de la Santa Cruz). It was at this time that the mosque was renamed and the apse was added.
The edifice was then known as Mezquita Bab-al-Mardum, deriving its name from the city gate Bab al-Mardum.
Built in 999 in Toledo, this building is a rarity in that it is in much the same state as it was when it was originally built. The building is a small square structure. It measures roughly 8 m × 8 m. Four columns capped with Visigothic capitals divide the interior into nine compartments. Covering each of these bays is a vault that has a distinctive design that is unique unto itself. The central vault is higher than the other ones and acts as a cupola for the structure. Each vault employs the use of ribs to create the designs that make them unique. Each of them follows the basic ideas of Islamic design. The ribs typically do not cross in the center, an idea that is seen in many Muslim designs. Some of the designs are more rectilinear while others embrace the curved forms of the vault more prominently. Within each one is a piece of their culture and tradition of building. The columns and the capitals both had been taken from previous buildings and are therefore known as spolia.
The building is constructed of brick and small stones. These techniques are a reflection of both the local building tradition as well as the influence from the caliphate in Córdoba. The influence of the caliphate can be seen in the brickwork on the facade of the building which resembles those seen at the Cathedral–Mosque of Córdoba. Originally the Eastern wall was a continuous stretch of brick and served as the qibla wall for the mosque. Also located along this side would have been a mihrab used for worship. The other three facades are articulated by three-bay arcades. All are similar, but individual in their decoration.
The Western wall which served as the main entrance is unique in how the arcade is articulated. This facade has a lobed arch, horseshoe arch, and a wider version of a horseshoe arch. Brickwork arches provide the decoration for the facade which are influenced by the architecture in Córdoba. In later years a Mudejar semi-circular apse was added. In the process of the addition the qibla wall and mihrab were lost. The use of the mudejar style provided a smooth transition from the original structure to the apse, as the addition uses the same style of decoration and materials as the original. The continuation of the arch motif is an important link between the two sections of the building.
Monte d"Accoddi is a Neolithic archaeological site in northern Sardinia, located in the territory of Sassari. The site consists of a massive raised stone platform thought to have been an altar. It was constructed by the Ozieri culture or earlier, with the oldest parts dated to around 4,000–3,650 BC.
The site was discovered in 1954 in a field owned by the Segni family. No chambers or entrances to the mound have been found, leading to the presumption it was an altar, a temple or a step pyramid. It may have also served an observational function, as its square plan is coordinated with the cardinal points of the compass.
The initial Ozieri structure was abandoned or destroyed around 3000 BC, with traces of fire found in the archeological evidence. Around 2800 BC the remains of the original structure were completely covered with a layered mixture of earth and stone, and large blocks of limestone were then applied to establish a second platform, truncated by a step pyramid (36 m × 29 m, about 10 m in height), accessible by means of a second ramp, 42 m long, built over the older one. This second temple resembles contemporary Mesopotamian ziggurats, and is attributed to the Abealzu-Filigosa culture.
Archeological excavations from the chalcolithic Abealzu-Filigosa layers indicate the Monte d"Accoddi was used for animal sacrifice, with the remains of sheep, cattle, and swine recovered in near equal proportions. It is among the earliest known sacrificial sites in Western Europe.
The site appears to have been abandoned again around 1800 BC, at the onset of the Nuragic age.
The monument was partially reconstructed during the 1980s. It is open to the public and accessible by the old route of SS131 highway, near the hamlet of Ottava. It is 14,9 km from Sassari and 45 km from Alghero. There is no public transportation to the site. The opening times vary throughout the year.
