Bhojpur is famous for the incomplete Bhojeśvar temple dedicated to Shiva. The temple houses one of the largest liṅga-s in India, 5.5 m (18 ft) tall and 2.3 m (7.5 ft) in circumference. It is crafted out a single rock. The building is under the protection of the Archaeological Survey of India.
The attribution of the temple to Bhoja is based on the testimony of Merutuṅga, who reports in the Prabandhacintāmaṇi that Bhoja bestowed on the poet Māgha “all the merit of the new Bhojasvāmin temple that he was about to build himself”, and then “set out for the country of Mālava”. The style of the sculpture on the building confirms an early to mid-eleventh-century date for the structure.
The building as it stands consists of the inner cella or garbhagṛha, supported by massive pillars, surmounted with an elegant corbelled dome. The outer walls and superstructure of the temple were never built.
