Rosewood High School

Rosewood High School seems to be a state of the art school with practically everything.

This includes:
 * Lacrosse training facilities (Aria drops off Mike in the Pilot episode)
 * Full-length indoor swimming pool with stadium seating
 * Computer laboratory
 * Auditorium for school plays
 * A separate auditorium for school assemblies that doubles as a trophy room
 * State-of-the-art chemistry laboratory
 * Music classroom

Behind the Scenes

 * Lord Byng Secondary School in Vancouver, British Columbia doubles as Rosewood High. (This can be seen by enlarging the photo above.)

 * In EscApe From New York, Rosewood High doubled as the hospital in New York.

TV Series - Book Series Comparison
Main Article: Rosewood Day School 
 * In the book series, "Rosewood Day" is a private school with students 1st-12th grade in it.
 * In the TV show, the students have no dress code while in the books they have a Strict School Uniform (e.g. Girls wear skirts and button up shirts, blouse or jumpers to school while guys wear blazers and ties).
 * Ella Montgomery is not a teacher in the books while in the TV series she is a substitute and later a full-time replacement for Ezra Fitz, who left for a teaching position in Hollis.
 * In the books, the song 1812 Overture piped through the PA speakers. It is played in between classes because it's "mentally stimulating."
