Sri Ramakrishna Math and Mission, the Order founded by Swami Vivekananda, to carry far and wide, the teachings of Sri Ramakrishna which constitute the core of India's oldest philosophy - Vedanta, has its headquarters at Belur, on the western bank of the river Ganga, near Calcutta.

The main attraction at Belur Math is the temple of Sri Ramakrishna Paramhansa. Towards the end of 1897, during their trip to noth-west India, Swami Vivekananda had long discussions with Swami Vijnanananda regarding the construction of this temple to be designed under the influence of Indian art and architecture. Later one day, while strolling at the banks of the Ganga at Belur, Swamiji asked Swami Vijnanananda, who was an engineer before joining the Order, to prepare designs for the temple. The spot where the temple would stand was also decided by Swami Vivekananda. Though Swami Shivananda laid the foundation stone for the temple in March 1921, there was a change in the exact spot and it had to be relaid in May 1935, this time by Swami Vijnanananda himself. The construction of the temple took four years and around Rs.8,00,000. Of this, Rs.6,00,000 was donated by Ms. Hellen Rubel, an American devotee. Ms. Rubel and Ms. Worster - the major contributors to the temple, were facilitated by the then Mayor of Calcutta at the famous Town Hall. The temple was opened in 1938. 

Among the other landmarks at Belur Math are the temples of Sri Sarada Devi, Swami Vivekananda and Swami Brahmananda, standing on the spots where their last rites were performed. The room where Swami Vivekananda stayed is also open to the public for darshan.

An added attraction of Belur Math is the Ramakrishna Museum.
