How to encrypt a hospital?

The fear of another huge war, made more and more destructive by nuclear weapons, determined the second half of the XX. century. After the Second World War everybody around the globe tried to prepare for a potential nuclear attack.

The expansion of the Hospital in the Rock was ordered because of this fear: two new wards were made, and a new extension was built in front of the entrance – these were finished by 1952. The hospital was made nuclear-proof between 1958 and 1962: chemical filters, a ventilation system capable of internal air circulating, and new generators and water tanks were added. Furthermore a new entrance was made, where decontamination could be carried out. The facility was classified by the code LOSK0101/1.

The Virus Vaccine Production Institute

The work of the Hospital in the Rock was not finished after the 1944-45 Siege of Budapest ended, it was still needed throughout spring. After all this though – it was never meant to be opened permanently – it was closed and emptied.

Many opposed this decision, and petitioned for the further use of the hospital in some form. It was around this time that a former staff member of the Hospital in the Rock, Dr. József Born appeared, a person who knew well the potential the facility held. The momentarily abandoned building, had the perfect conditions for a laboratory.
