The construction of Roman temple in Córdoba began during the reign of Emperor Claudius (41-54 AD) and ended some forty years later, during the reign of Emperor Domitian (81-96 CE). Presumably it was dedicated to the imperial cult. The temple underwent some changes in the 2nd century, reforms that coincide with the relocation of the colonial forum.
In the area had already been found architectural elements, such as drums of columns, capitals, etc. all in marble, so the area was known as los marmolejos. This area of Córdoba could become between the 1st century and the 2nd century, as the provincial forum of the Colonia Patricia, title that received the city during the Roman rule.
The building was situated on a podium and consisted of six columns on its front facade and ten columns on each side. Currently, the only remains left of the building are its foundation, the stairs, the altar and some shafts of columns and capitals.References:
The Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
