Liberty High School was built in 1918 and opened in 1922. It is located in the geographical center of Bethlehem, Pennsylvania, in the Lehigh Valley region of the state. Originally, Liberty was called Bethlehem High School. The name was changed after rival Freedom High School was built. The school was named Liberty after the Liberty ships that returned to Pennsylvania after World War I. Up until Liberty's recent remodel, the school was composed of three classroom buildings, two buildings with four floors and one science center with two. Also, there were many additions added over the years including a pool and two gyms.
