Kanthkot Fort became the destination of Mulraj of Anhilwad Patan in the middle of the 10th century. When Tailap of Kalyan Ketah put pressure on Mulraj, he escaped to this fort. Kanthkot Fort was known as Kanthadurg at the time. The Raja of Kanthagam, perhaps Kanthkot, from the west is mentioned in the twelfth century (1143) as siding with the Nagor chief against Kumarpal of Anhilwad Patan. Kanthkot Fort was recognised as the Vaghelas' capital in the thirteenth century. Mod and Manai Samma seized Kanthkot Fort at the turn of the century. Vaghela not only gave Mod Kanthkot Fort, but he also arranged for his daughter to marry Mod's son, Sad. Sad then established himself as the ruler of Kanthkot Fort, making it his capital and residing there. Sade's son Ful changed the fort's name to Kanthadurg once more. Muzaffar (1390-1411) seized and controlled Kanthkot Fort as the fifteenth century (1410) began.
Today, the Kanthkot fort is open to visitors who can explore its winding staircases, hidden chambers, and spectacular views.
