Purandar is about 40 kms south-east of Pune and some 10kms south-west of Sasawad. Perched on a gigantic mountain mass, its height above sea-level is 1398 metres and about 700 metres above the plain at its foot. It really comprises two fortresses - Purandar, the stronger and more important of the two, and Vajragarh, small sister fort situated on a ridge running out east of it. Purandar has two parts: the upper or Balekilla with precipitous sides all around and the lower part or machi about 300 metres above the plain. On the north side of the lower part there is a broad terrace comprising the cantonment area of the fortifications.
There are many monuments, old and new, on the terrace. Towards the east of the terrace, beyond a narrow ridge, lies the fort of Vajragarh, also called Rudramal. From the cantonment are of the terrace a winding path leads to the upper fort. The approach is commanded by the Dilli Darwaza, the main gate. The most important monuments, on the summit of the hill is the old temple of Kedareshwar.
