The miniature model of Mount Kailasa (เขาไกรลาสจำลอง; ), the mythical abode of Shiva, was built during the reign of King Rama IV. The miniature mountain was used as a setting for an important ceremony called the royal tonsure ceremony. This ancient rite of passage would be performed for the royal prince and princess around the age of thirteen. The ceremony, sometimes lasting seven days of festivities, involves a purifying bath and the cutting of the traditional topknot hair of the royal child. The latter act was done by the king himself, the hair is later thrown into the Chao Phraya river as an offering. For this purpose there is a miniature palace on the summit for the ceremony to take place. the lower part of the mountain is populated with stone sculptures of miniature mythical animals of the Himavanta Forest. The mount is situated behind the walk way between the Dusit Maha Prasat Throne Hall and Ho Plueng Krueng. This area is considered part of the Inner Court and is not opened to the public.
