The Central Seminary was built in the 1930s and was designed by Fernando Ocampo. The plan of the seminary was configured in the form of the letter E, with courtyards bisecting the wings. The boxy building had an elongated frontage assembling a continuous band of balconies and windows on the second and third level. The structure's horizontally oriented massing was broken by an engaged central section at the main entrance and two other similar treatments at the end portions. An art deco relief, bud-like finials, and a tableau embellished the stepped pylon at the entrance.
