Old Photo of Watson's Hotel on 1867

Watson's Hotel, now known as the Esplanade Mansion, is India's oldest surviving cast iron building. It is located in the Kala Ghoda area of Mumbai (Bombay). Named after its original owner, John Watson, the building was fabricated in England and constructed on site between 1860 and 1863.

The hotel was leased on 26 August 1867 for the terms of 999 years at yearly rent of Rupees 92 and 12 annas to Abdul Haq. It was closed in the 1960s and was later subdivided and partitioned into smaller cubicles that were let out on rent as homes and offices. Neglect of the building has resulted in decay and, despite its listing as a Grade II–A heritage structure, the building is now in a dilapidated state.
