Despite its prominent visibility from Bataan, the Corregidor Post Hospital was not specially targeted by the Japanese artillery. Indeed there are suggestions (unverified) that it was not accorded target status, and was hit only incidentally. It took no role during the siege, all patients and  medical personnel having been  transferred already to the 1000 bed capacity Malinta Tunnel Hospital.

The destruction of the Hospital that one sees on Corregidor was accomplished largely by scrappers who had access to Corregidor by dubious arrangements with the military authorities.  Thereafter, the elements and military training on the island hastened the building's demise.
