In Bhojpur, Raja Bhoj is said to have built three large earthen dams and created a massive reservoir that was later destroyed by Sultan Hoshang Shah of Malwa. On the banks of this man-made lake, he commissioned a large Shiva temple, called the Bhojeshwar temple, with a massive shivling measuring 7.5 feet (2.3 m) in height and 17.8 feet (5.4 m) in circumference. It is set on a square platform, whose sides measure 21.5 feet (6.6 m).The total height of the lingam, including the platform is over 40 feet (12 m)! This makes it the tallest in the country. It is made of three limestone blocks superimposed on each other.
