Birmingham, Huntingdon County, Pennsylvania
Birmingham is a borough in Huntingdon County, Pennsylvania, United States. The population was 90 at the 2010 census. 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. Legend among the local residents is that it was once in consideration to be the state capital. 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. In 1853, the Mountain Female Seminary opened in Birmingham as a boarding school for girls. In its earliest years, the school benefited from the ease of transportation afforded by the passage of the Pennsylvania railroad through Birmingham. Currently, the school still operates as Grier School, a  boarding school for girls. The East Coast earthquake on August 23, 2011 caused a rockslide along Route 453 in Birmingham. Geography.
