Akash Bhairav, the temple of the Kirat King slain during the epic battle of Mahabharata.............

The Kirats are the first documented rulers of the Kathmandu Valley. The remains of their palace are said to be in Patan near Hiranyavarna Mahavihara (called "Patukodon").   
The first and best remembered king was Yalambar. Legend has it that when Yalamber heard about the great battle that was fought in the distant plains of Kurukshetra, he too wanted to participate in this battle. So donning a fierce and silver mask of Bhairab, the Lord of Terror, he went with his army. At the battle field he was met by Lord Krishna who asked him whose side he was on. He replied that he would take the side of the   losing army.Lord Krishna fearing that the fearsome warrior would join the Kauravas, decapacited his head with such force that it flew past the Himalayas to Kathmandu and rested at the place where the Akash Bhairab temple now stands. The temple, a three storey structure now stands in the busy square of Indra Chowk. The mask of Bhairab is taken.
