At the Madrid hospital in Fuenlabrada they are building something that, from the outside, doesn’t look like much: a two-story building with three-meter-thick concrete walls, a roof that had to be opened with a crane, and foundations designed to support dozens of tons of machinery. Inside that bunker is kept one of the most valuable assets that Spanish public health has received in decades. That technological jewel that they protect with concrete is the proton accelerator donated by the Amancio Ortega Foundation: one of the ten latest generation machines that the founder of Inditex agreed to surrender to the public health system in October 2021 in a donation valued at 280 million euros. The objective is to install them in seven autonomous communities and transform the cancer treatment in Spain. A custom concrete bunker. Building this type of technology is not like installing a scanner or an X-ray device. The radiation emitted by a proton accelerator requires the construction of a specific building to act as a containment barrier. In Fuenlabrada that has become concrete walls three meters thick. The construction of the bunker began in July 2024 and the regional government has allocated 13 million euros to finance the construction of the new building. According to a statement of the Community of Madrid, the result is a two-story structure with more than 2,000 square meters of total surface area, partially connected to the already existing oncology area. The ground floor, of about 1,300 square meters, will house the diagnosis, treatment and patient preparation areas. The first floor, of 875 square meters, will be used for maintenance, supplies, medical offices and training. The pieces that entered through the roof. The proton therapy equipment is made up of two main elements, and both are already inside the bunker. The first is the Cyclotron, the device that generates and accelerates protons that are then used as “ammunition” against cancer cells. It measures eight meters tall and weighs almost 50 tons. To place it in place, it was necessary to open the roof of the building and use a heavy crane to install it inside the bunker. The second element is the Gantry, the rotating arm that directs the radiation towards the tumor with millimeter precision. This component exceeds 11 meters in height and reaches 75 tons in weight. Its complete rotation capacity is what allows the tumor to be attacked from any angle and reduce damage to healthy surrounding tissues. In this video The installation process of one of these machines in the New York Proton Center is shown, using a process very similar to that used in the Fuenlabrada hospital. Protons change the rules of the game. Proton therapy is not an improved version of conventional radiotherapy, but rather it works with high-energy proton beams capable of concentrating the impact exactly on the tumor and stopping there, without continuing to irradiate the tissues behind. This makes it an especially useful tool for treat hard-to-reach tumorssuch as brain tumors, on neckspinal cord, lung, ocular, sarcomas, etc., and for pediatric patients, where minimize side effects In the long term it is critical. Until now, in Spain there were only two centers with this technology, both private: the Hospital Quirón de Pozuelo de Alarcón and the Clínica Universidad de Navarra. Thanks to the donation from the Amancio Ortega Foundation10 new proton therapy centers will soon be inaugurated in public hospitals distributed throughout the national territory. A nuclear reactor in the basement. The arrival of the two main pieces does not mean that the equipment is ready to use. Only the main elements have been installed in place. Over the next 12 months, engineers will carry out the complete assembly of both components, their calibration and the commissioning of the accelerator. It is a process that involves continuous testing to check and monitor radiation before any patient is approached. In December 2025, the Nuclear Safety Council (CSN) already issued a favorable authorization, with conditions, for the radioactive facility of the hospital: an essential requirement before the unit can operate. It won’t be the first, but it adds up.. The one in Fuenlabrada will not be the first public health device of these characteristics to offer proton therapy treatments. The Galicia center, in Santiago de Compostela, is the most advanced in its installation and already has the Proteus One accelerator. In this case, two bunkers have been necessary (one for treatment and the other for research) and the first patients are expected to be treated at the end of 2026 or beginning of 2027, with capacity for 250 patients per year per room. The Madrid hospital, for its part, aims that its unit will be operational throughout the first quarter of 2027.
