San Agustin Church

San Agustin Church (Spanish: Iglesia de la Inmaculada Concepción de María de San Agustín) is a Roman Catholic church under the auspices of The Order of St. Augustine, located inside the historic walled city of Intramuros in Manila.

In 1993, San Agustin Church was one of four Philippine churches constructed during the Spanish colonial period to be designated as a World Heritage Site by UNESCO, under the collective title Baroque Churches of the Philippines. It was named a National Historical Landmark by the Philippine government in 1976.

In the setting, a large chamber beneath the church was one of the hideouts for the ancient conspiracy known as Leviticus.

Derp-related Activities
This is the primary site of the San Agustin Siege that actually encompassed almost all of Intramuros.

The Leviticus hid their ritual as a midnight vigil held by multiple local schools. This same vigil had tipped off the Malleus Maleficarum of their gathering, and they began to move against them. They had several agents hidden in their gathering, including a certain Priest. At the same time, Derpman had finally received confirmation of their hideout, and decided to act immediately. The Derps were gathered to infiltrate the catacombs to rescue Sheila, and possibly to end their enmity with the secret cult.

The Derps and the Malleus worked together after an agent tried to kill Hyung-Tae Park and the Priest, and they coordinated their attacks. The Derps infiltrated from both within the San Agustin church and a secret path in the Baluarte, while the Malleus used a hidden route from the underground dungeons of the Manila Cathedral. Derpman made a large portion of the student body leave, and they timed their confrontation when there were very few people in the church.

Underneath the church, the Derps engaged the Leviticus and they rescued Shiela before the large group of the Malleus Maleficarum arrived. Marlon beheaded the leader of Leviticus, and the Derps escaped in the ensuing gunfight. The Malleus took over the fight and eventually defeated the enemy cult.

The large chamber and the parish itself is now presumably under Malleus control.
