I was curious about this building, understanding that it should have played a significant role in town.
Well, as you may read in the link below, it seems to be a still working factory, and that, in the center of a town, it's, today, a remarkable exception.
Facing and overlooking Portalegre there's a mount with a cross in its top, with the best views of the area.
On its slope, and easily accessible, there's a chapel from the 17th century that... I don't know!
We arrived there at nightfall, received by dog's barking, with clothes drying by the chapel's entrance and... we left. What is really that?
