One side of the square consists of a range of buildings occupied by persons in civil employments under the Company, such as writers in public offices.

Bagh area is near the Hooghly River in the western part of Central Kolkata and is a square built around the old Lal Dighi tank.

Bagh (or Dalhousie Square as it was formerly known) was created as the center of the British East India Company's trading post along the banks of the Hooghly River.

In the summer of 1756, Nawab Siraj ud-Daulah of Bengal, Bihar and Orissa launched an attack on the British town for the company's decision to strengthen the fortifications around it.

A number of corporations and institutions opened offices and headquarters in and around the square, giving it its role as the central business district of the city.

In 1912, the capital of the British Raj was officially moved to New Delhi, but the majority of the financial and political institutions in the area remained until the late 1920s.

On the eighth of December 1930, three revolutionaries, Benoy, Badal and Dinesh, stormed the building and fatally shot the Inspector General of Prisons, N.S.

This area is also a major commercial district with the offices of HSBC at Hong Kong House and the Great Eastern Hotel.

The church is home to beautiful stained glass windows and paintings as well as the mausoleum of Job Charnock, the man who founded modern Kolkata.

Bagh also has a statue of famous philanthropist Maharaja Lakshmeshwar Singh of Darbhanga (1858–1898), sculpted by Edward Onslow Ford.
