A long time ago, back when the romans ruled over Catalunya, there used to be a river which brought life and richness to the surrounding city of Barcino. Birds, reptiles, fish, and mammals roamed freely around marshy wet lands as the river collected its last waters on its way to the sea, cleaning and filtering the water as it went. As time passed Barcino grew, fell, rose, and over again, tuning to Barchinona, Barshiluna, and finally Barcelona. Unfortunately these changes didn’t go unnoticed to the surrounding territory and soon the ecosystem started being reduced, modified, and ultimately transformed. Farm land, flour mills, bridges, and buildings started damaging its natural balance as it gave way to the emergence of the mighty city of Barcelona.
