The temple of Baidyanath or Shiva is the most important of all the temples in the courtyard. The temple faces the east and is a plain stone structure with a pyramidal tower, 72 feet tall.

The top contains three ascending shaped gold vessels that are compactly set, and were donated by the Maharaja of Giddhaur. Besides these pitcher shaped vessels, there is a Punchsula (Five knives in Tridenta shape), which is rare. In the inner top there is an eight pettaled lotus jewel called Chandrakanta Mani.

The lingam installed inside, is of a cylindrical forming about 5 inches in diameter and projects about 4 inches from the centre of a large slab of basalt. It is not possible to ascertain how much of the lingam is buried. The top is broken and has uneven surface.

There are different porches in the temple. One porch leads to the cell where the lingam is fixed. The second porch is in front with a row of pillars spanned by blocks of basalt and on the right side there is a sandstone image of nandi.

There are bells fixed in the ceiling and pilgrims are supposed to pull the bell ropes to announce their approach to the divinity.

To the east of the northern verandah of the temple there is a large masonry vat into which flows the water and milk offered to the lingam. The liquid in it is essentially a mix of milk, sandal paste and washing of flowers, which impart to it a fragrant smell and is treated as highly sacred.
