 The most important of the other chapels in the complex is the capilla abierta (open chapel) which is dedicated to Saint Joseph.This structure is one of many built in Mexico in the first half of the 16th century in monasteries, and were usually meant for the saying of mass and other religious activities associated with the mass conversion of the native population at that time.It is possible that Hernán Cortés had this particular chapel built during the time he lived in Cuernavaca.
