The Municipal Corporation Building, Mumbai located in South Mumbai in Maharashtra, India is a Grade IIA heritage building (‘V’ shaped as viewed from top) opposite to the Chatrapati Shivaji Terminus (a UNESCO World heritage site) at the junction of Dadabhai Naoroji Road and Mahapalika Marg. It is also known as the Bombay Municipal Corporation Building, or BMC building for short.
As the name suggests, the building houses the civic body that governs the city of Mumbai, which is now named the Brihanmumbai Mahanagar Palika (Marathi: बृहन्मुंबई महानगर पालिका) or the Municipal Corporation of Greater Mumbai and which has as its motto, "यतो धर्मस्ततो जय" (Sanskrit: Yato Dharmastato Jaya or, Where there is Righteousness, there shall be Victory), inscribed on the banner of its Coat of Arms. It is said to be the largest civic organization in the country and covers an area of 434 km2 (167.6 sq mi) Sir Pherozeshah Mehta and Sir Dinshaw Wacha prominent citizens were members of the Municipal Corporation.
Two designs were considered for the building; one of the Gothic designs done by F. W. Stevens and the other in the Indo-Saracenic design presented by Robert Fellowes Chisholm. The Gothic design was finally selected. The building was completed in 1893. The building is known for its 255 ft (77.7 m) tall tower. The chief architectural feature is the central dome that rises to a height of 71.5 m (234.6 ft). The gable has a huge winged allegorical figure representing the 'urbs prima in Indis', the first city of India as it was to be known then. The richly molded and paneled Council Chamber has a ceiling of unpolished teak. Records also support that at these environs Phansi Talao or Gallows Tank, where public hangings took place, was located. During the period 1100 to 1500 AD the architecture of churches constructed with ornamental arches with ribs supported by buttresses resulted in the subsequent idea of the framed structural design with grandeur and monumentality during the renaissance period of 1500–1700 AD, as the distinct style; the Bombay Municipal Corporation building, the Victoria Terminus, the Rajabai tower and theUniversity of Bombay are some examples of this style. The old style of dome construction was also revived and became popular. The period from 1750 onwards was considered to be the period of modern architecture. The Gothic architecture with controlled composition custom–made to the climatic extremes of the city hascusped window arches and elaborately domed corner towers.The BMC was created in 1865 and Arthur Crawford was its first Municipal Commissioner. The Municipality was initially housed in a modest building at the terminus of Girgaum Road. In 1870, it was shifted to a building on the Esplanade, located between Watson Hotel and the Sassoon Mechanics Institute where the present Army & Navy building is situated. On December 9, 1884, the foundation stone for the new building of the Bombay Municipal Corporation was laid opposite Victoria Terminus now known as Chatrapati Shivaji Terminus, by the then Viceroy, Lord Ripon.

The restoration plan for the 125 year old BMC Gothic structure envisages a) restoration of interiors and the exterior – from the roof tiles to the exquisite Minton tiles inside and to stained glass work and b) strengthening several wooden beams. In the first phase the structure would be restored to its original glory involving replacement of broken tiles, repair of statues,and removal of plants and moss.
The subsequent phases of restoration would involve a) reorganization of office space within the building to improve the operational efficiency of staff members, b) 'Citizens Facilitation Centre' and party offices in the ground floor and c) Corporation Hall to be modified for a larger seating arrangement by including outer corridors and opening the wooden doors to increase its seating capacity from 200 to 300.
