On this mysterious terrain, behind high fences and strict security, the factory of the Dutch Army produced firearms, artillery and ammunition from 1895 onwards.
These are the ruins of an old stonefactory in the north of the Netherlands.
The construction of the Mont`Alto Sanatorium began in 1932. Due to the appearance of a large number of people who had contracted tubercolosis, it was necessary to expand the facilities, and these enlargement works were completed in 1958. This sanatorium was the last one built in Portugal.
My son and I visited this urbex location, an abandoned farm in my place of birth, in march 2015.
