When the World Heritage site we know as the Alamo opened in San Antonio as the Mission San Antonio de Valero, it wasn't the first iteration of the mission. Archeologists now think it was initially founded at a different site in 1718, then moved about a mile away from 1719 until 1724, when a hurricane forced the mission to move a final time. And the researchers also believe that the earliest Alamo predecessor has been found.
