First of all, thank you very much!
I can give you few answers... This was shot in Seixal - Portugal. It's a little city with a big fishing and Cork processing tradition.
This house/property belonged to one of the most rich families related to the cork business. They owned a huge processing factory nearby, which is being rehabilitated right now. A museum has been built for example, and some other parts of it have been transformed into restaurants, a music school and Art galleries.
This building still stands, even if crumbling, as an ode to a relatively prosperous recent past, reminding us all that nothing lasts forever.
