Interesting Story of Origin of Gwalior
According to local sayings, Gwalior owes its name to a sage of former times, who used to live on that hill where Gwalior fort is today stood. It was the eighth century, when Suraj Sen, a prince of the Kachhwaha clan, who is said to have lost his way in the jungle. On that secluded hill, he met an old man, the sage Gwalipa, whose influence almost took him by surprise.
Upon asking the sage for some drinking water, the sage led him to a pond. The waters of this pond not only quenched his thirst but cured him of leprosy. Out of gratefulness, the prince wished to offer the sage something in return, and the sage asked him to build a wall on the hill to protect the other sages from wild animals which often disturbed their Yagnas (or pujas or holy prayers).
Suraj Sen, later on, built a palace inside the fort, which had been named “Gwalior” after the sage. And eventually, the city which grew around the fort took the same name. That pond which cured his leprosy was also named Suraj Kund or Suraj pond
