The most popular and significant place of worship in Mumbai is the Shree Siddhivinayak Ganapati Mandir situated at Prabhadevi. This temple was first consecrated on Thursday, 19th November 1801.

The idol of Shree Siddhivinayak is of black stone and is 2.5 feet high and 2 feet wide, with the trunk turning to the right.

Flanking the deity on both sides are Riddhi & Siddhi, goddesses signifying sanctity, fulfillment, prosperity and riches. Etched on the forehead of the deity is an eye, which resembles the third eye of Lord Shiva.

Riddhi and Siddhi are Goddesses of success, riches and prosperity. The auspicious idol of Shree Siddhivinayak with its trunk bent towards the right is unique, as the trunk is usually found curving leftwards.

The old temple had an ancient architectural style, consisting of a hall, a sanctum sanctorum, some free open space, the temple's administrative office to the right and a water tank in the front.

The temple’s renovation commenced in 1990. It was completed in 3 years with an expense of Rupees three crores. The main stones used were marble and pink granite.

The temple was designed to be a fine architectural example. Thus, a 200 year old temple was renovated and restored into a magnificent, multistoried and palace like temple.

The summit of the temple is a cluster of 37 gold-plated crowns, with the main 12 feet crown, 3 five feet crowns and 33 Three and a half feet crowns.

The temple's crown installation and Kumbhabhishekam ceremony took place on 13 June 1994 with the auspicious hands of Shree Shankaracharya Bharti Tirtha Mahaswamiji of Dakshinamnay Shree Sharadha Pitha, Shringeri.

There is a sannidhi for Lord Anjaneya in the temple.

An estimated 1.5 to 2 lakh people visit the temple every Tuesday.
