• The oldest buildings in the US have interesting and diverse histories.
• Fort Snelling in Minnesota, Castillo de San Marcos in Florida, and Fort Mackinac in Michigan were all started for military reasons.
• Some of the oldest buildings are log cabins, like the Joel Eddins House in Alabama and the Louis Arriandeaux Log House in Iowa.

The oldest architecture in the US ranges from military forts to Catholic missions to log cabins.

From New Mexico's Acomo Pueblo, which has 250 structures that have been continuously inhabited since the 12th century, to the White Horse Tavern, a bar in Newport, Rhode Island, that opened its doors in 1673, America's buildings are as historic as they are diverse.
