Surprisingly, the most magical places I visited in Peru were not the world-famous Inca ruins at Machu Picchu or other places, but rather the Spanish churches and convents. After all, the Inca had no writing, so while their ruins showed an incredible knowledge of masonry that could withstand severe earthquakes, there was little that aroused my imagination.

A place that did, however, was the giant convent of Santa Catalina in Arequipa. It occupied something like a whole square mile that was walled off from the city that surrounded it and had a warren of narrow pedestrian walkways.

I spent an entire day, from morning to late afternoon, wandering around the grounds of Santa Catalina, with its monastic cells, courtyards, kitchens, chapels, and even a strange room where the faces of nuns who had died were painted on canvases and displayed.

As Christianity begins its slow fade in the Western World, I begin to look upon religious monuments of the past as being every bit as interesting as that of ancient civilizations. In Peru, I loved visiting the old churches, convents, and museums of ecclesiastic art. I must have attended a dozen masses, just because they took place while I visited.

I took dozens of photos which I could have shown here, because Santa Catalina mesmerized me. If you should happen to go to Peru, you will probably wind up in Cusco and Machu Picchu, but for your health, it is better to go first to a place where you will not be so afflicted by the dread soroche (altitude sickness). Arequipa, at 7,660 feet (2,335 meters) is a good place to prepare yourself.

And not just because of Santa Catalina!
