It was built during 1713-1720 CE by Balaji Vishwanath, the first Peshwa of Maratha Empire. Visapur fort was built much later than Lohagad but the histories of the two forts are closely linked.
In 1818, when reducing the Peshwa's forts, the strength of Lohagad and its fame as the treasury of the Maratha kingdom, caused the English to make special preparations for its attack. A detachment of 380 European and 800 native soldiers, with a battering train, summoned from Konkan, were joined by artillery from Chakan, and two other British battalions. On 4 March 1818, Visapur was attacked and occupied. Making use of its higher elevation and proximity to Lohagad, the British troops set up their cannons on Visapur and bombarded Lohagad, forcing the Marathas to flee. Thus, in 1818, Lohagad-Visapur was taken over by the British in 1818 AD and placed under the command of a Colonel Prother. Considering, the strategic importance of Visapur, both in the north Konkan and the south Deccan gateways were blown up now a few huts, nothing was left standing. In contrast, most of Lohagad fort is still intact source Wikipedia.
Visapur is the opposite ridge to the famous Lohagad. Not many trek this fort. For a trekker its absolute thrill. The base village for both the forts is the same. However the trek to Visapur actually starts from the base of Lohagad fort. Hence it’s a trek in a trek – double delight.
Over the years the pakka roads have been made right till the base village – in the name of development. Every year during monsoon thousands flock to Lohagad for a one day PICNIC.
