The original school building opened in 1952 and the current building opened in 1967. The original building became Park Hill Junior High and later Plaza Middle School, the district's 6th grade school. Plaza is now a 6-8 grade middle school. In the late 1990s a new gymnasium was built on the west side of the building to replace the original gym, which is now used primarily for practices and school dances. Around this same time, an auditorium was also built adjacent to the new gym. Since 1998, Park Hill has won nine
wrestling state championships, two
volleyball state championships, and the 2003
football state championship, as well as a cheerleading state championship in 2014. The Lady Trojans won the 2018 girls soccer state championship. == Facilities ==
