Erfoud, a desert town in eastern Morocco, is often seen as the last stop before the endless dunes of the Sahara begin. But this oasis holds more than just a convenient location. Known as the "Gateway to the Desert," Erfoud is steeped in history that predates the modern borders of Morocco. It was once a French colonial outpost, and today, its dusty streets and adobe buildings offer a glimpse into a slower, older way of life that still shapes the region’s identity.

The nearby Templo de San Cayetano, built by mine owners in the mid-1700s, is a stunning example of baroque design, lined with gilded altars and intricate woodwork.
