The temple is situated on the top and bottom of Koyla Hill. Harsidhi Matatji is also known as Ambica Mataji and Kalki Mataji. The local people call her Harshad Mata.
The ancient temple on top of the Koyla hill, has the same construction styles of the Navlakha Temple of the Chalukya Dynasty in Ghumali, where as the temple in the bottom of the hill is quite modern.On the northern side of the temple is the fire pit, where Harshad Mata used to roast and eat the King of Minalpur Prabhatsen.
Roast & eat??? Yes, the story goes like this, that before about 2000 years, the capital of the Chavda Kingdom was Minalpur, there the king was Prabhat sen Chavda. This minalpur was a main port and trading used to be done with foreign shores.
Once during the holy festival of Navaratri, the 7 wives of Prabhatsen were playing garba. So Jagdamba Mataji from the Koyal hill, also done ornaments and fine clothes and took the appearance of a beautiful lady, came down to play the Ras.v
