Situated in the vicinity of Chhatrapati Shivaji Terminus, the Mumbai General Post Office (GPO) is a paradigm of Indo-Saracenic architecture.

[1] The building has an area of 120,000 square feet (11,000 m2) and replaced the current Central Telegraph Office at Flora Fountain as the new GPO.

The chief feature of the architecture of this building is an ethereal central hall which rises up to the great dome.

Due to its proximity to Chhatrapati Shivaji Maharaj Terminus, Mumbai's central station, it is ideally situated to dispatch and receive mail to and from other cities in India.

It also controls the smaller post offices in Mumbai, issues stamps, and prints new inland letterheads and postcards.
