.."abandoned" for some decades
..step 2
..the practice of step 3 at Praça Duque de Saldanha
1 - The absence of maintenance for some decades.
2 - After the last tenant leaves the building, the main door should be closed with an iron chain with a padlock. This may seem like a peculiar measure, but it sends the message that the building is beyond salvation.
3 - The opening of some windows to accelerate the process of decay.
4 - Now is time for the removal of some tiles from the roof in order to accelerate the infiltration of water.
5 - Finally, if steps 1, 3 and 4 are insufficient or slow, there is always the possibility of a “spontaneous combustion”.
This methodology has been applied with plenty of success for some decades with the passive cooperation and understanding of the (in)competent Portuguese authorities.
