More than 11,000 years ago, a small stone staircase at Karahan Tepe is quietly reshaping how we think about the earliest architecture on Earth. In a time long before cities, writing, or fully developed farming, these steps suggest that people were already designing complex architecture. The discovery offers a rare glimpse into how the first monumental environments may have guided ritual, gathering, and experience, hinting that the origins of architecture begin not with shelter, but with intention.
