The Red Fort was built by Shahjahan in the 17th century in what is now Old Delhi, or the Walled City. It is a UNESCO World Heritage Site and another architecture icon of Indias capital. Originally, River Yamuna flew by the fort and replenished the moats which surround the walls of the fort. However, land was reclaimed from the river for construction purposes in modern India. It may not look like a architectural marvel today, but the fact that it has remained strong and stood the test of times for over 3 centuries is testimony to the brilliance of the architecture.
