In the 16th century, the authorities of Córdoba decided to improve the condition of the entrance to the city due to the deteriorated state of the existing gate. With this goal in mind, on February 18, 1572, mayor Alonso Gonzalez de Arteaga issued the order to build the Bridge Gate.
Reasons given focused on the fact that it was one of the city's main gates, handling a high volume of movement in terms of both people and supplies. In addition to enlarging the gateway, the city's officials wished to improve the artistic merits of the gate as part of an urban renewal.
Bridge Gate construction was started by Francisco de Montalbán although few months later, in 1571, Hernán Ruiz III which took over the works. Complications arose with respect to the design of the door, leading to a spike in the expected cost: the initial budget of 1400 ducats tripled to 3100. Work apparently stopped for a four year period until 1576, when Hernán Ruiz resumed his work. Possibly due to the indebtedness of the City Council of Cordoba and general lack of funds, the project remained was unfinished.
In 1912, under the reign of Alfonso XIII, the area in which the Puerta del Puente was located was stripped of its walls and rebuilt in 1928 as a memorial gate, repeating on the inner side forms the outer side. In the late fifties the level of all the land bordering the door, until the original ground level was restored, when neighbouring buildings were lowered.
In the early twenty-first century, the first restoration of the Puerta del Puente took place, at which point archaeological excavations took place. Further restorative work continued in 2005.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.
