Etymology of Mahakali Cave
Earlier these were referred as "Kondivite" or "Kondivti" caves as these caves were near Kondivti village. At present these caves are locally known as Mahakali caves. Name "Mahakali" in turn comes from the Hindu temple nearby; thus it is somewhat misleading regarding this ancient Buddhist monastery.

Cave 1, 2 & 3 - This is the first cave group when entering through the main entrance. There are 3 caves connected with each other. The middle one is the main cave and it consists of an open courtyard with a pillared portico, a rectangular hall with a seat for an icon on the western side. A stupa has been carved on the back wall behind this seat.

Entrance door of the hall is carved with Chaitya windows above the lintel. It is decorated with various patterns on its jambs. On either side of this unfinished central Chaitya cave, are provided pillared entrances into cave 1 and 3. These entrances are at lower depth than the entrance of the Chaitya cave which is in middle of these two lower entrances.

Cave 4 or the Vihara Cave - This vihara is entered through a verandah supported on 4 pillars and 2 pilasters. A flight of 5 steps leads to this entrance. There are 3 entrances leading into a rectangular hall. The vihara is bereft of any decoration of sculptural embellishment.

Cave 5 or the Chaitya Cave - This is the main cave of the group and probably the oldest excavation at the site. It faces east and entrance is provided from a rectangular hall.
