Shri Mayureshwar Temple, located in Morgaon, Maharashtra, is the primary and most significant shrine of the Ashtavinayak yatra, dedicated to Lord Ganesha as the slayer of the demon Sindhuvasur. It is a historically significant 14th–17th-century site featuring a unique peacock-riding idol, symbolizing Ganesha as Mayureshwar. 

Key Details of Mayureshwar Temple:

Location: Situated in Morgaon village (Pune district), about 70–80 km from Pune city, near the Karha River.

Significance: It is the starting and ending point of the Ashtavinayak pilgrimage (eight Ganesha temples) and is regarded as the most important of the eight.

Deity Form: The idol is known as Mayureshwar (or Moreshwar) because Lord Ganesha took this form riding a peacock (mayur or mor) to slay the demon Sindhuvasur.

Architecture & Features: The temple is built of black stone and fortified with minaret-like pillars at four corners, blending Hindu and Islamic styles. Inside, a 6-foot-tall Nandi (bull) faces the Ganesha idol, which is unusual as Nandi is typically associated with Lord Shiva.

Idol Description: The main deity is three-eyed, seated on a pedestal, with its trunk turned left.

Key Festivals: Ganesh Chaturthi and Maghi Ganeshotsav (birthday of Ganesha) are celebrated with immense enthusiasm.

Association with Legends: The temple is closely tied to the saint Morya Gosavi, a staunch devotee of this form of Ganesha.
