Birmingham is the site of the Birmingham Window, a geologic structure created by a Paleozoic thrust fault.
Birmingham's early settler, John Cadwallader, settled on a hill above the Little Juniata River and made plans to establish a large city. In the first several decades of the 19th century, the village grew quickly as a hub for commerce being carried on the Little Juniata River and on the nearby Pennsylvania Canal. By 1850, the Pennsylvania Railroad had passed through the valley. The development of the railroad diminished the importance of Birmingham as a trading hub since the railroad's nearby hubs in Tyrone and Altoona grew quickly on land that was better suited for development.
