The United States is a comparatively young country, but one with a rich and diverse history. From the ancient villages of New Mexico’s Pueblo people and the early Spanish settlers in Florida, to the Russian traders of Alaska and 19th-century missionaries in Utah, each of the 50 states has its own story to tell.

There’s no better way to trace this history than through buildings, which is why we’ve mapped out the oldest intact building in each US state. Whether they’re cottages, grand mansions, fortresses or churches, these historic sites offer us a glimpse into the early days of the regions. They help us to understand what brought early inhabitants to the state – and what their lives might have been like.
