One of my favourite activities while travelling is to visit abandoned spots and explore.
The first one is called Termas Radium, a deactivated radioactive water treatment center,
A deactivated mine in Alentejo, called S. Domingos mine, where the water has been corroded by the mining efforts.
And lastly, some houses in different locations that I got to explore, including a mansion they call the “Disney” mansion, in Sintra.
