Today it is office. Most famous for certain ghost stories, but myths aside it is just a building that is fairly unremarkable in the context of Madrid. Better places to visit and only worth a look if already in the area.

It is a building with a lot of history and a especially spooky one. I took the haunted Madrid tour of BeeYou travel. Amazing!!! Highly recommended if you want to discover Madrid with a unique way.

Nothing really to see there now. Just a building from outside. One can't enter the building anymore as there is some office running there now.

A small highlight in Madrid but totally worth it to visit and learn about.

There is seven chimneys but no access at all because they turn into business or company facility
