The **Yamuna River** flows behind the **Taj Mahal**, one of the most famous buildings in the world. The Taj Mahal is located in **Agra**, a city in the Indian state of Uttar Pradesh.

The river plays a very important role in the setting and beauty of the Taj Mahal. When you look at the monument from the back, you can see the calm waters of the Yamuna. In the past, this river was also used as part of the water supply system for the gardens and fountains of the Taj.

The Taj Mahal was built by **Mughal Emperor Shah Jahan** in memory of his wife **Mumtaz Mahal**. It is a symbol of love and a masterpiece of Mughal architecture. The peaceful flow of the Yamuna behind the white marble building makes the view even more magical, especially during sunrise and sunset.

The Yamuna is one of the major rivers in India. It starts from the Yamunotri Glacier in the Himalayas and flows through several states. It is also a tributary of the Ganges River.

So, if someone asks, “Which river flows behind the Taj Mahal?” — the correct and clear answer is: **Yamuna River**.
