A fort and town was established at the foothills of Girnar hill during reign of the Maurya Empire and continued to be used during Gupta period, but it lost its importance when the capital of Saurashtra region was moved from Junagadh to Vallabhi by Maitraka.

[3] After several Chudasamas of Vamansthali had ruled, a woodcutter one day managed to cut his way through the forest and came to a place where stone walls and a gate existed.

[9] If this story is to be believed, either Graharipu rediscovered an ancient stronghold or else after he had built the fort, it was abandoned and afterwards found again by a later ruler Navaghana who transferred Chudasama capital from Vamansthali to Junagadh.

The parapets on the east, where the place is commanded by higher ground, have been raised at least three times to give cover against the increasingly long range of projectiles.

There are two Wells in the Uparkot — the Adi Kadi Vav, said to have been built in ancient times by the maids of the Chudasama rulers, is descended by a long flight of steps; and the Navghan Kuvo, cut to a great depth in the soft rock, and with a circular staircase.
