A big square was created for the first time, the main square, (today Constitution Square),and the convents of Victoria and Trinidad (Trinity) were founded. The 16th and 17th Centuries were characterized by the crisis that was provoked by the expulsion of the Moors who had converted to Christianity on one hand, and on the other by bad harvests, flooding caused by the overflowing of the river Guadalmedina, and by epidemics.
