Felipe II wanted to build an XXL channel from Madrid to Lisbon. Now the city has recovered it inspired by ancient Egypt

When the workers are excavated in a city with the solera and patrimonial wealth of Madrid the ground can become a box of surprises. The team in charge of the expansion of Metro Line 11, which during its excavations at the future Madrid Rio station recently proved it. He found himself With a wall of the Real Canal del Manzanares, the Gran river path dreamed by Felipe II. The structure has value, that was clear from the beginning, but it was so delicate and was in such a complicated area that a doubt arose: how to rescue it?

Simple: ‘Looking’ to Ancient Egypt.

Underground Award. If Spanish architects know something, it is that when you hurt a shovel in a city and excavas enough it is not strange that archaeological remains begin to emerge. It has happened in the works of Expansion of line 11 of the Madrid Metro. A few months ago The operators who are responsible for horating the ground for the future underground network and the Madrid Rio station found more than rocks: they located remains of the Real Canal del Manzanares.

Curious yes, surprising no. The finding is interesting and will help us know better The old channeling who aspired to connect Madrid and Lisbon with barges, but did not catch off experts. “It has been no surprise to meet this section of the channel here,” I commented In spring a The country Archaeologist Esther Andreu. It is not the first finding in the environment and experts have been in charge of keeping tables and examining the area with laser scanners.

What is the real channel? Maybe The craziest dream From Felipe II, that one day, back in the 16th century, he wondered why he could not have Madrid his own port with the Atlantic. Sounds macarronic, but what the monarch had in mind was to imitate the model of locks and channels he had seen In Flanders and create a river route that connected Madrid with Aranjuez and then continue through the Tagus to Lisbon … and America. The project, huge, required a 600 km navigable route capable of saving 650 m slope, as Pedro Gargantilla requires in ABC.

With honey on the lips. The project advanced and In 1584 Felipe II himself came to travel from Madrid to Aranjuez to verify in situ the progress of the company. However, neither its real effort, nor that of the engineer behind the project, Juan Bautista AntonelliNor the implication of the monarchs that followed Felipe II on the throne (especially Carlos III) served to make the structure reach the size with which the Austria dreamed. Stayed in a channel of 22 kilometers of extension (far from the initial objective), 14 meters wide and three of draft, with ten locks, header, jetty and houses for workers.

Against the project they played several factors, in addition to their considerable technical complexity. The first varapalo was the death of Antonelli in 1588, which happened complications with financing, the distancing Politician with Portugal and, already advanced time, in the 19th century, the growing competition of the railroad, which caused the infrastructure Stay in disuse. That did not prevent the Royal Channel from remembered as an emblematic project whose remains, as Metro has verified, continue to rest under the feet of Madrid.

What to do with the remains? The million dollar question. The wall has a heritage and historical value, that is clear, so it would not be unreasonable to do the same as in other stations and expose the vestiges in Madrid Río itself. But one thing is to remove and handle wood remains, small stones or metal parts and a very different manipulate a structure of several tons. How to move it? How to get it out of its original site without destroying it?

The questions are brought because, like Andreu explains in ABCin the unearthed section the Royal Channel was about nine meters wide and 1.5 deep. “It was not very deep, it passed parallel to the Manzanares channel. The water flowed because it was built at the same water table of the river,” he recalls. Before the Brete of having to move that huge structure without deteriorating it, those responsible for the project made a curious decision: ‘look’ to ancient Egypt.

“A very complicated order”. The company perhaps scared other archaeologists, but not Miguel Ángel López Marcoswith extensive experience in the recovery of the colossi of Amenophis III in Luxor and that it has already been involved in the ‘rescue’ of other pieces of the Madrid heritage, such as The last vestiges from the San Gil barracks. That callus and previous knowledge have helped him to face the Real Canal project, a task that admits, it was not simple.

“The commission was very complicated by the situation of the wall embedded in the tunnel and the characteristics of the fragile and mechanical resistance,” account.

Metal cage and steel rollers. How did he solve it? The first conclusion reached by López Marcos is that “the extraction should be in block.” “Disassembly would cause the disintegration of the wall, which does not have the necessary consistency,” Clarify The expert before pointing out that conventional engineering lacks resources to “guarantee” the conservation of that kind of structures. It is nothing new. The same challenge has already been found in Egypt, where he can often resort to heavy machinery that facilitates the task.

To solve it López Marcos and his companions had to pull ingenuity. The team designed a protective cage, a shield that allowed it to dig under the structure and dispose of a base with steel bars. Everything firm enough to endure a 14 tons structure. Hydraulic beams and cats allowed them to advance the operation and descend the remains of the wall at a sufficient height to move it to a crane truck. To facilitate the movement of the cage with the stones the team also handled steel rollers.

Objective: Expose it to the public. “The load has also been manually executed on the truck-sharing that has then carried the remains to the tunnel output well where the crane-torre has raised the historical wall to the storage area to proceed to the end of the works of the Madrid River station,” concludes. The goal? Restore and prepare the vestiges to show them in a showcase when the station has been completed. A way of paying tribute to the old channel that wanted to make Madrid a powerful port city.
