Sinhagad -- where valour is etched on every stone and the soil has turned red seeped by the blood of martyrs! From the time when a Koli chieftain, Nag Naik stoutly defended this fort (AD 1328) against the might of the Muhammad-bin-Tughlaq for nine months to Jaswant Singh, Aurangzeb's commander, who dragged his guns up the fort's steep shoulders to avenge the insult to Shaista Khan, who was rebuffed by Shivaji, this fort has been infused by tales of bravery.
It was here that Shivaji's general, Tanaji Malusare launched an attack to recall the fort. In the resulting battle, Tanaji valiantly laid down his life, but captured the fort. A grieving Shivaji is known to have said,"Gad ala pan sinh gela" (The fort is won but the lion has gone). And this is how the fort got its name: sinh (lion's) gad (fort).
