Mahim is an ethnically and religiously diverse town and has a Hindu temple, church, mosque and Parsi fire-temple existing within a few meters of each other.

The name Mahim is derived from the ancient Mahikavati meaning "miraculous" in Sanskrit.

After the British acquired Mumbai, they built the Mahim Fort here to protect themselves from the Marathas.

The causeway connecting Mahim and Bandra (corrupted from "Bunder" meaning port in Persian) was completed in 1845 at a cost of Rs.

Other forts in Mumbai and Salsette Island include Sion, Worli, Sewri and Mazagaon.

The largest ethnic minority group being Goans (Portuguese descent) followed by South Indians (mostly from Karnataka, Kerala and Tamilnadu).

Mahim is considered to be Mumbai's ethnically, religiously and linguistically most diverse town.

During the colonial era, the Portuguese built a watchtower called Castella de Aguada on the northern side.

It forms the boundary between the city (Churchgate to Mahim) and suburbs (Bandra to Dahisar) of Mumbai.

The waters of the creek are foul smelling due to the dumping of untreated industrial effluents upstream.

The station is an important Junction as it connects Western Suburbs (till Goregaon) with Harbour line (CSMT to Kings Circle).

The British East India Company, which governed Bombay at that time, refused to fund the project.

This led Lady Jeejeebhoy, wife of the first baronet Sir Jamsetjee Jejeebhoy, to donate the entire amount of ₹157,000/- on the condition that the government would not charge a toll for its use or disturb the Koli community who lived around the area.

It is not to be confused with the Bandra–Worli Sea Link, a major infrastructural project opened on 30 June 2009 which is designed to ease traffic across the causeway by building another bridge across the Mahim Bay.
