The Manila Central Post Office is the central post office of the city of Manila, Philippines. It is the head office of the Philippine Postal Corporation, and houses the country’s main mail sorting-distribution operations.
Designed by Juan M. Arellano, the post office building was built in neoclassical architecture in 1926. It was severely damaged in World War II, and rebuilt in 1946 preserving most of its original design.[1]
It is located in the Intramuros district of the city, at the bank of the Pasig River. The building’s main entrance faces the Liwasang Bonifacio.
