The Students' Activity Centre, popularly known as the Barn, is located next to the Three Concrete Silos Ruins. The nickname 'The Barn' given to the Students' Activity Centre denotes that the ground near the silos would have been utilized to raise livestock at the Farm School. The Barn, like the other newly designated monuments, was designated a historic site in 2019 (Jamaica National Heritage Trust, 2019). Also, the Barn accommodates several businesses serving the school population and the general public. The Barn also serves as a venue for student events.
