Columbine High School (CHS) is a high school in Littleton, Colorado, United States. The school is part of the Jefferson County Public Schools district. The school is located at 6201 South Pierce Street. The official school colors are blue and silver.
Columbine High School opened in the fall of 1973. It was named after the surrounding community of Columbine, which in turn was named after the state flower of Colorado: the columbine. The school's first principal was Gerald Difford. There was no senior class during the school's first year; its first graduating class was in 1975. The school colors were selected through a vote by students at Ken Caryl Middle School and Bear Creek High School, who were the first to attend Columbine High School when it opened in 1973.
The school has undergone significant renovations since it first opened: in 1995, with the addition of a new cafeteria and library; in 1999-2000 (after the massacre), with interior renovations to the corridors, cafeteria, and former library; and in the early 2000s, with the addition of the new HOPE Columbine Memorial Library and a memorial on the site.
Columbine High School was the site of one of the deadliest mass shootings in modern United States history. The shooting occurred on April 20, 1999, when two senior students Eric Harris and Dylan Klebold killed twelve students and a teacher, and wounded 23 others, before they both committed suicide. The massacre made headlines both nationally and internationally, making Columbine a household name, and causing a moral panic in American high schools.
After the shooting, classes at Columbine were held at nearby Chatfield Senior High for the remaining three weeks of that school year.
After the shooting, Columbine completely demolished its library, located above the cafeteria, since it was the site where the majority of the deaths occurred. The site was then turned into a memorial ceiling and atrium; a new, larger library was built on the hill where the shooting began and dedicated to the memory of the victims.
