Military camp.
This is the most likely location for the future new Lisbon airport.
The day the airport is in Alcochete, the tranquility of this area will disappear. There will be more traffic and confusion.
If the airport is in the Alcochete shooting range, this shooting range will be moved to Mértola, a small town in the Alentejo region near Spain and which is more than 200 km from Alcochete.
Well, the shooting range employees will be moved to a location more than 200 km away, far from the capital, and probably from their families.
And, living in Alcochete and Mértola has nothing to do with each other. I'm not saying that Alcochete is better or worse, but they are very different places, the climate is different and Alcochete belongs to the Lisbon area and Mértola is more isolated. This situation may not please everyone because it is too big a change.
