The new school would consist of 100 acres (as opposed to the current building's 30-40 acres) and is intended to educate 900 to over 1000 students. Students were officially allowed into the new Charlestown High School on January 4, 2010. The whole school was expected to be finished by no later than 2011. The last basketball game played in Charlestown High School's Dunn Arena was on February 26, 2010, the arena was 55 years old. It was torn down along with many other parts of the original school for the new schools construction.The new state-of-the-art facility includes a massive Wireless Internet network, a smart board in every classroom, a new athletic complex, new baseball and softball fields, a much larger cafeteria, a much larger library, and could hold a total of 1050 students. Many of the lights within the school include motion sensors as well. The school also included its own filtration system which is said to have some of the cleanest water in the City of Charlestown. There were also many features that made the school energy efficient. The school officially held its 'Dedication Ceremony' and allowed tours of the new high school to the public on October 31, 2010, and the new high school was almost 100% complete at that time. Many people who had gone to the school when it was originally built, back in the mid-1950s, attended the event and were quite pleased with all of the changes made within the school.
