Swayambhunath is among the oldest religious sites in Nepal. According to the Gopālarājavaṃśāvalī, it was founded by the great-grandfather of King Mānadeva (464-505 CE), King Vṛsadeva, about the beginning of the 5th century CE. This seems to be confirmed by a damaged stone inscription found at the site, which indicates that King Vrsadeva ordered work done in 640 CE.[3]
Although the site is considered Buddhist, the place is revered by both Buddhists and Hindus. Numerous Hindu monarch followers are known to have paid their homage to the temple, including Pratap Malla, the powerful king of Kathmandu, who is responsible for the construction of the eastern stairway in the 17th century.
