Portsmouth Christian Academy is located on 50 acres along the Bellamy River in Dover. The lower school facility is currently housed in one building which contains a large main school complex of four distinct sections (preschool, elementary, junior high, and administration). The main complex includes a three-story building with two fully equipped science labs for the junior high science program, a computer center, two art studios, a library, and a music conservatory.

The upper school consists of two newly constructed buildings which contain state-of-the-art science and computer labs, as well as a new library. New programs include: Digital Photography and Computer Aided Design (CAD).

Upper school students participate in NHIAA Class "S" athletic competition, which includes softball, soccer and volleyball teams at both Varsity and Junior Varsity levels. The athletic program is supported by two gymnasiums. Our main gymnasium has adjacent locker areas and athletic offices, and is attached to the lower school academic building.
