When the Japanese invaded the Philippines in 1941 during the second world war, many residents used the sanctum of the retreat as a place to shelter.  However, the Japanese showed no mercy and attacked the former seminary full force, causing major damage to the structure.  The priests and staff who ran he retreat as well as many residents were killed by the invading soldiers, many of them who did not die in the initial attack were beheaded.
