The first ¡®skyscraper¡¯ of the Middle Ages was in Toledo

On account of the bears, wild boar and other animals lurking in the forests that stretched some 30 kilometers around Toledo, the capital of the Visigothic Kingdom, the chief of the province ¨C or Dux ¨C decided to build a grand two-story building for hunting purposes at the start of the 6th century.

One hundred years later, a church, a warehouse and a dike to contain the water from the mountains were built beside the castle-like structure and enclosed by a wall more than two meters thick. Many years later this area, which covered five hectares, would become the hamlet of Arisgotas, within the municipal boundaries of Orgaz, in Toledo province.

A team of more than 100 experts from several universities led by Isabel Mar¨ªa S¨¢nchez Ramos, from the Institute of Archeology of University College London, have spent the last three years reconstructing this enigmatic enclave. At Los Hitos archeological site, researchers have dug up more than 100 bodies, including that of the Dux, and estimated that the height of the tallest building was over 12 meters. It was not until the ninth century that this record was trumped by the 20-meter-high minaret in C¨®rdoba, designed by Moorish architects.

Much later, in the 16th century, the local peasants in Arisgotas kept coming across massive stones as they worked the land ¨C the stones, or hitos, that would give the place its name. These blocks were typically? taken into town and used in the construction of the houses there. In the first decade of the 20th century, a local known as ¡°T¨ªo Sim¨®n¡± discovered an alabaster tomb and, in 1938, the government of the Spanish Republic sent a team of experts to investigate.

But it wasn¡¯t until the 1970s that archeologists began to excavate and, with their findings, developed the theory that the tall building had been a church surrounded by stone coffins and tombs.

In 2016, fresh excavations began, allowing experts to establish that the unusually high building had, in fact, been a palace of a member of the nobility of Toledo. Jorge Mor¨ªn, director of the dig, explains that the building¡¯s height was calculated using Pythagoras¡¯s technique for doubling the area of a square, and at over 12 meters it was the first ¡°skyscraper¡± of the Early Middle Ages. ¡°It took centuries to go higher,¡± he says. ¡°There is indisputable evidence of abutments used to increase the wall height with views to the vault and to an upper floor, also confirmed by evidence of a staircase by which the upper floor would have been accessed.¡±

The Dux¡¯s tomb was found in the building¡¯s doorway and his bones indicate he was a man who spent much of his time on horseback. His burial place is surrounded by the tombs of other notable figures and their families, including women. At the foot of the door to the church, the skeletons of nine children have been found, buried along with small pots that would serve to feed them in the afterlife.

Other remains have still to be analyzed but could belong to monks. A massive tombstone has also been unearthed, belonging to either a king or a Dux whose name ends in the letters ¡°-do.¡±

Experts estimate that another 10 years are needed to unearth all the mysteries buried beneath

It has not yet been established whose body was excavated from the main tomb, only that he was a nobleman and that, given the system of choosing Visigothic Kings, he could have been in the running for the crown. But for now at least this is no more than speculation. What does seem clear is that the complex was built during the reign of Athanagild and Goiswintha (551-567) and was expanded during the reign of Reccared I (586-601)

In 2017, the archeologists found a temple adjacent to the castle-like structure with only one nave and two porticos. Its interior was decorated in marble and it housed a number of coffins fashioned in alabaster and granite. According to specialists, this could have been a private place used only by the nobility, complete with family vaults.

Antonio Malalana, director of research methodology at CEU-San Pablo University, explains that at the next stage of the dig, bodies will be unearthed in a more protected environment to avoid contaminating the DNA. ¡°It¡¯s very complicated work which obliges those involved to be properly equipped and covered,¡± he says.

Work being carried out under the watchful eye of Felix Teichner from Marburg University in Germany has just revealed a further four underground structures, around 20 meters long and 10 meters wide.

In the ninth century, during the Al-Andalus period, the complex was subject to great changes. The church, for example, was shifted to face Mecca and turned into a mosque with a mihrab ¨C a semi-circular niche in the wall indicating the direction the faithful should pray in. Stairs were added to the pavilion while doors were walled up. The complex was used as a fortified space for harnesses and tack for horses. With King Alfonso VI¡¯s conquest of Toledo in 1085, it fell into ruin and became a quarry for the locals.

Now, experts estimate that another 10 years will be required to unearth all the mysteries buried beneath.
