The History of Warren Township High School District 121

  • The first schoolhouse was erected in 1838.  A second school was constructed in 1840. The sOriginal Building chool was later relocated one quarter of a mile down the road. Other elementary schools were soon built. A combined school at Gurnee Grade School was built in 1908, which housed both the high school and grade school. The high school district organized in 1915 and was established formally in 1917.

    The first high school building was erected at a cost of $112,000 in the spring of 1918 on O’Plaine Road, at that time known as High School Road. The first graduating class in the spring of 1918 graduated from the school building that was under construction. WTHS opened on its present site of O’Plaine Road in the fall of 1918 with an enrollment of 64 students and seven teachers.

    Additions to this structure were made in 1926, 1951, 1956, 1960, 1968, and 1974. This building was destroyed by a major fire on December 20, 1984 just prior to the winter break. At that point in time, all students and staff moved to the Lake Forest High School West Campus. From January 1985 until June 1987, the Lake Forest Campus was the educational facility for all the students of WTHS.  After the fire, facility construction began in May 1986 and was completed in mid-August 1987. Students and staff returned to the O’Plaine Campus in Gurnee for the first time since December 1984.

    Almond Campus Due to an enrollment growth, a second school facility was constructed on Almond Road.  The 1997-98 school year was the first time that WTHS operated an educational program using two buildings. The 9th and 10th grade students are primarily housed in the building on O’Plaine Road (O’Plaine Campus), while the 11th and 12th grade students primarily attend the Almond Road (Almond Campus) building. 

    Both campuses saw more building expansions and improvements in 2004, 2008 and 2012.  In 2009, Warren’s enrollment made it the largest high school in Lake County.Transportation

    A Transportation Center, located on Swanson Court in Gurnee, was constructed for bus and van services in 2013 and is currently sharing services with Gurnee School District 56.  Warren’s Transition Program opened at Gurnee Mills in 2015, which is a premiere special education post-high school program for special needs students ages 19-22 years old.
