a plan for two comprehensive high schools in Greenwich. This was voted down by the Representative Town Meeting (RTM), so the Board of Education instead approved one high school at Put's Hill. This project was approved for an estimated $9.8m which, at that time, was the largest single appropriation in Greenwich (the cost grew to $14.5m). The old campus eventually became the current Town Hall. This new campus on Put's Hill (along Hillside Road) is the current campus today. It is fifty-four acres with a student capacity of 2,750 which is expandable to 3,300. The students moved into the Hillside campus in 1970. Twenty years later, in 1990, the town added a new science wing, the Black Box Theater and additional classrooms, extended and refurbished the locker rooms, and renovated the auditorium, the swimming pool and the courtyard. The renovation added 90,000 square feet at a cost of $43,000,000. Then, in 2016, the school replaced the auditorium with new music rehearsal rooms and built a state-of-the-art Performing Arts Center.
