About
In the 14th century, Barcelona is experiencing one of its most prosperous moments. The city has grown to La Ribera, a fishing district in which the largest Marian temple ever known is built: Santa María del Mar. But the construction runs parallel to Arnau Estanyol, a serf of the land who, fleeing the abuses of The feudal lords of the countryside take refuge in Barcelona.
