Nestled along the Mandi-Kullu Highway at Bajaura, the Basheshar Mahadev Temple stands as a remarkable testament to the regions ancient heritage. The name “Basheshar” derives from the word “Vishveshara,” signifying the Lord of the Universe. As the largest stone temple in the Kullu Valley, this architectural marvel, constructed in the Pratihara style, exemplifies the distinctive Nagara style of temple construction prevalent in the region. Believed to date back to the 8th or 9th century A.D., the Basheshar Mahadev Temple shelters an ancient Shiva Linga within its Garbhagriha, radiating a profound aura that resonates with devotees. Despite being dedicated to Lord Shiva, the temple also hosts magnificent idols of Ganesha, Mahishasurmardini form of of Devi Durga, Vishnu, and various other deities, reflecting the diverse streams of worship once prevalent in the region. An intriguing feature is the absence of the customary Nandi Maharaj idol in this Shiva temple, possibly due to the impact of the 1905 earthquake.

Fragments of the broken idol can still be observed near one corner of the temple, echoing a rare occurrence. A closer examination reveals an ancient Tankri script inscription, dated 1673, just outside the Garbhagriha door—an enduring record of land donation by Raja Shyam Sen of Mandi. Under the protection of the Archaeological Survey of India (ASI), this temple stands proudly as a designated National Monument, offering a captivating glimpse into the rich historical tapestry of the region, where diverse streams of Hinduism coexisted harmoniously alongside the worship of local deities.
