The old buildings have always fascinated me, especially the industrial ones of the past.
It has always intrigued me to understand technological advancement and industrial progress, imagining how work could have been a century ago or more. Certainly not so easy.
Industrial archeology is often hidden in buildings that we sometimes see every day passing through our cities or towns; we are often used to seeing them and we don't pay attention.
This is an old furnace in my city, I think it dates back to the late 1800s.
