Tumacacori Mission ruins
Made up of adobe, wood, and plaster (Hey! This must be where modern-day architects found inspiration to build the entire of Phoenix!) the Tumacacori Mission ruins have been a Southern Arizona landmark since 1691, when the village was established. Missionaries, settlers, and soldiers have all passed through, making their mark on the rich culture that exists there presently. Not much remains of the early settlements, but today the historical site is preserved and protected by the National Park Service and it’s open to the public.
