Just southwest of Patagonia [1] along Highway 82, near milepost 15.9, there’s a shrine built into the rock face of the mountain. It’s worth taking a few minutes to climb the steps and take a peek inside, where there will likely be candles burning and messages written to the dead.
The shrine was built in the 1940s by the Telles family, whose matriarch vowed she would construct and keep up the shrine if her five boys returned safely from World War II. They did, and the shrine is still in use today.
