Hiei-zan
The Siege of Mount Hiei was a battle of the Sengoku period of Japan fought between Oda Nobunaga and the sōhei (warrior monks) of the monasteries of Mount Hiei near Kyoto on September 30, 1571. It is said that Nobunaga Oda killed all the monks, scholars, priests, and children that lived on the mountain in this battle. However, recent excavations have pointed out that many of the facilities may have been abolished before this and the destruction was less than some historical sources indicate.
