The CTHS building originally served as a church.
In 1889 the congregation of the Lower White Oak Christian Church sold its church building to a Mennonite Congregation in Congerville for $400 and built a frame church in the new Village of Carlock. In 1914 the Carlock Christian Church moved its church building across the alley to the north and built an impressive brick church on the current site.
In 1915 the old frame Carlock Christian Church building was sold to the new high school district for $500. The church building was moved to just east of the Carlock Grade School, (where the school’s asphalt parking lot exists today). The church building was expanded (at a cost of $4,800) and served as the CTHS until consolidation with Unit 5 in 1948. Thirty-one senior classes (1918 – 1948) graduated from this high school.
Note: After consolidation with Unit 5, the old CTHS building continued to serve as extra classrooms for the Carlock Grade School, until this old church building was razed in 1956. This author attended second grade in the old CTHS building in1954. Our classroom was in what my mother (CTHS class of 1942) tells me was originally the CTHS “English Room”.
