The General Post Office, Mumbai, the largest one in India serves as  the central post office of this metropolis. It is one of the finest Colonial buildings built  by  the British to  house Post Office  to serve  the  people  then. The British India government  also built GPO in cities  like  Calcutta (Kolkata), Madras (Chennai), etc. Only recently it was restored back to  old glory by INTACH's  professional  conservation  engineers. The old structure, prior  restoration  work began, had remained uncared for a long time resulting  in damages  in many parts  of the building.

Inspiration came from the work  of Robert Chisholm (of Madras Presidency). Both architects used Gol Gumbaz, Bijapur, KA as a model to build domes in public structures.
