The interior part of Portugal suffers a lot with emigration, abroad and to the littoral.
To contribute to the promotion of these areas is common the public organizations to plan regular events there.
That's what took me to Portalegre, a city that, otherwise, would be far for my priorities.
It is was a good idea, and I really loved the city.
30 years ago I passed, without stopping, by Portalegre (to be precise, I stopped just the time enough to take a general picture). Now, I WENT to Portalegre, and visited it. Comparing two pictures, took almost in the same position, it's easy to understand the slow evolution suffered by most of the cities inland. That is bad, in terms of development, but good, in terms of preservation.
