Indragad Fort, in Karambeli village, about fifteen miles north of Umbargaon, on a wooded hill from two to three hundred feet high, stands near the south bank of the Kalu river about two miles from the sea coast. To the east and west of the fort the hill is very steep, but in 1818 the forest came near enough in places to cover an attacking force. It is also commanded by a detached hill about 400 yards to the south-east.

The fort is very small not more than 180 feet by 120. In 1818 it had round towers for defence, the works being about twenty feet high and ten thick. The body of the rampart was in good repair, but the parapet was only four feet thick and out of order. The fort had two entrances, both protected by a strong wall lower than the works with which it was connected. Within the fort were two tolerable buildings for stores and barracks and two ruined reservoirs. Underneath the fortifications were about nineteen cells of different sizes. In 1862 the fort was ruinous. Indragad was taken in 1780 by Lieut. Welsh of General Goddard's army, the brilliant captor of Parnera and Bagvada in south Surat. [Grant Duff's Marathas, 435.] The cells are the remains of an old religious settlement. They are said to be plain without figures or inscriptions, but have not yet been properly examined.
