1953 Map of Mars

About this map

The Baltimore and Ohio railroad corridor anchors this mid-century look at the border between Butler and Allegheny counties, connecting the boroughs of Callery and Mars. The landscape transitions from the established agricultural and early industrial base of Cranberry and Adams townships toward the growing residential patterns emerging near Wexford and Bradford Woods. This era shows the significant presence of the Thorn Hill Industrial School and the early infrastructure of the Pennsylvania Turnpike as it began to reshape local transit.
