Ranjangaon is a village located at a
              distance of about 50 km from Pune, enroute to Aurangabad in Maharashtra, and it houses a
              shrine to Mahaganapati. 
              Ranjangaoncha Mahaganapati  is
              considered to be one of the Ashta Vinayak shrines
              of Maharashtra, celebrating eight instances of legends related to Ganesha.
              
              Legend has it that a demon by name Tripurasura
              built three powerful citadels (the evil Tripuram forts); with a boon of invincibility
              granted to him by Shiva he caused suffering to all beings in the heavens and on earth.
              Upon hearing the fervent appeals of the Gods, Shiva intervened, and realized that he could
              not defeat the demon. It was upon hearing Narada Muni's advice that Shiva
              saluted Ganesha and then shot a single arrow that pierced through the
              citadels, bringing an end to the demon. 
              Shiva, the slayer of the Tripura citadels is enshrined
              at Bhimashankaram nearby. 
              A variation of this legend is
              commonly known in South India. Ganesha is said to have caused the axle in
              Shiva's chariot to break, as the latter headed to battle the demon
              without saluting Ganesha before he set out. Upon realizing his act of omission, Shiva
              saluted his son Ganesha, and then proceded victoriously to a short battle against the
              powerful demon. (See Acharapakkam 
              - an ancient temple in Tamilnadu glorified by the 1st millennium tamil hymns enshrining
              Shiva associated with this legend, as well as Tiruvirkolam
              and Tiruvatikai - both over 1200
              years old, associated with the legend of Tripurasamhaaram).
              (The tamil lines of 15th century saint poet Arunagirinathar: 'Muppuram eri seida,
              Acchivan urai ratham, acchadu podi seida athi deera'  where he describes Ganesha as
              the valiant hero, who caused the axle of Shiva's chariot to crumble to dust, as Shiva
              headed out to destroy Tripurasura, narrate this legend.)
              The Temple:  Mahaganapati is
              portrayed, seated on a lotus, flanked by his consorts Siddhi and Ridhi. The temple dates
              back to the period of Peshwa Madhav Rao.
              Festivals: As with all other Vinayak
              temples, Ganesha Chaturti is celebrated in great splendor here.
