The large-roofed churches have only one name and on one side, usually on the south, is the cloister area for the monks. Most of the cloisters have or had murals, large gardens and fountains. Decorative elements in both vary, often mixing different trends that were prevalent in Europe at the time, such as rose windows common on French cathedrals, portals similar to those in Spain and even Islamic style triangular altars. A number of hidden elements such as certain numbers important to native beliefs can be found in the churches, such as the number of stairs and aspects of the decorative figures. It is unknown whether these were tolerated by the friars or whether they were added clandestinely.
