Some guy's villa - whoever was rich enough to indulge in posh architecture and had the inclination to show off, probably did so during that XIX century or before. The villa was converted into a clinic or something for lung diseases, and served as such for a long time. I remember when I was teaching I had to go to be checked there - a sanitary precaution asked of anyone working with kids. Later this function went to zzzzz.
Later* the main road cut between the villa and the antituberculosis dispensary (which is actually a clinic) and the villa was abandoned, not being in the same yard anymore. During the nineties, some refugees squatted in it and burned most of the hardwood, including the staircase. Then it was taken by some art association as the museum of destruction, led probably by some NGO (if the association itself isn't such an NGO).
The picture is from the long photo walk on 06-VIII-2019., but it looked equally ruined nine years before and two years later.

* actually no, it was laid in 1975; the villa was abandoned in the early nineties.
