Parashar Caves
Panhala city in Kolhapur district was traditionally considered the residence of Maharishi Parashar. The Karvir or Kolhapur Puran, a modern compilation, mentions Panhala as Pannagalay (home of serpents). In old inscriptions the name appears as Pranlak and Padmanal. The caves at Panhala are supposed to be the caves where the sage Parashar lived. Moropant, an 18th-century Marathi poet, wrote most of his work in these caves. Moropant's Birthplace is also Panhala. These caves are mentioned in the Karvir Puraan as tirths.
