Swayambhunath (Devnagari: स्वयम्भूनाथ स्तुप; sometimes romanized Swoyambhunath) is an ancient religious complex atop a hill in the Kathmandu Valley, west of Kathmandu city. It is also known as the Monkey Temple as there are holy monkeys living in parts of the temple in the north-west. The Tibetan name for the site means 'Sublime Trees' (Wylie:Phags.pa Shing.kun), for the many varieties of trees found on the hill. However, Shing.kun may be a corruption of the local Newari name for the complex, Singgu, meaning 'self-sprung'.[1] Swayambhunath is one of the most sacred sites of Buddhist pilgrimage in Nepal, second only to Boudhanath.

The Swayambhunath complex consists of a stupa, a variety of shrines and temples, including a Tibetan monastery, a museum and a library. The stupa has Buddha's eyes and eyebrows painted on. Between them, there is something painted which looks like the nose - but is the Nepali symbol of 'unity', in the main Nepali language dialect. There are also shops, restaurants and hostels. The site has two access points: a long stairway, claimed to have 365 steps, leading directly to the main platform of the temple, which is from the top of the hill to the east; and a car road around the hill from the south leading to the southwest entrance. The first sight on reaching the top of the stairway is the Vajra. Tsultrim Allione describes the experience:

We were breathless and sweating as we stumbled up the last steep steps and practically fell upon the biggest vajra (thunder-bolt scepter) that I have ever seen. Behind this vajra was the vast, round, white dome of the stupa, like a full solid skirt, at the top of which were two giant Buddha eyes wisely looking out over the peaceful valley which was just beginning to come alive.
Much of Swayambhunath's iconography comes from the Vajrayana tradition of Tibetan Buddhism. However, the complex is also an important site for Buddhists of many schools, and is also revered by Hindus.
