While the core shrine is ancient, the outer structures and the Shikhara (tower) were added during the Maratha and Peshwa periods. The temple served as a spiritual fortress for the Maratha warriors. It is mentioned in the Shiva Purana as one of the most powerful Jyotirlingas, situated in the 'Dakini' country.

Maratha Craftsmanship and the Roman Bell

The temple architecture is a fine example of the Nagara style, characterized by its intricately carved pillars and a stepped Shikhara. A unique historical curiosity is the Massive Bell at the entrance, which features a cross and the year 1729. It was captured by the Marathas from the Portuguese at Bassein Fort and offered to the temple as a trophy of war. The temple walls feature carvings of humans, animals, and celestial beings that seem to 'dance' when the morning light hits the stones.

Legend tells of a demon named Tripurasura who caused chaos in the three worlds. At the request of the gods, Lord Shiva manifested as 'Bhima' (The Formidable) and annihilated the demon. The sweat from Shiva's body after the battle is said to have formed the River Bhima. Another legend links the site to Bhima, the son of Kumbhakarna, who tried to destroy the Jyotirlinga but was reduced to ashes by Shiva.

Worship at Bhimashankar is intimate; devotees are allowed to touch the Jyotirlinga during certain hours. The rituals are performed with the pure, cold mountain water. A visit is often completed by trekking to Nagphani (the highest point nearby) or Gupt Bhimashankar, making the worship an active engagement with the sacred geography of the Sahyadri mountains.

Maha Shivaratri is the primary festival, with thousands of pilgrims trekking up the hills. Tripuri Purnima is also celebrated with great fervor to commemorate the victory over Tripurasura. During the month of Shravan, the temple is crowded with 'Kawadiyas' (pilgrims carrying holy water).

The most enchanting modern folklore involves the **'Shekru'** (Malabar Giant Squirrel). Pilgrims believe that sighting the rare, large, rust-colored squirrel in the temple canopy is a sign of good luck and a blessing from the forest-lord Shiva. There is also a strong belief that the river Bhima is actually the 'Ganga of the South' and that its waters have the power to heal respiratory ailments due to the medicinal herbs it washes over in the forest. Many locals claim that during the heavy monsoon rains, the sound of the waterfalls around the temple echoes the chanting of 'Om Namah Shivaya'.
