Pune has two rivers, Mula and Mutha. Their confluence is located at a place called Sangamwadi in the middle of the city. (The word Sangam means "confluence"). After this point, the unified river is called Mula-Mutha.

A few kilometers before the confluence, the river Mula flows along a northern suburb called Aundh. Here, there is a historical stone structure located right at the riverbank. It is a canopied structure with a Shivalinga and Nandi. (Nandi is the divine bull mount of Lord Shiva). The structure is surrounded by a square stone wall. There are two entrances. One from the north, which faces the river, and the other from the south. 

There are ancient runic inscriptions carved on the stones, which are most fascinating. According to sources, it is believed that the canopied structure is a tomb of an unknown warrior. Other than this, not much information is available about it. In Hindu culture, such a tomb or memorial is called a Samadhi. Such memorials are often located next to rivers, lakes and other water bodies.

The tomb is a reminder of the grand honor given to the dead in all the cultures across the world. The ambience around the riverbank is peaceful and honours the memory of the unknown warrior.
