Kaathe Swayambhu Shree Gha Chaitya, also known as Kathesimbhu stupa or Kashi Swayambhu, is a scaled-down replica of the famous Swayambhunath Stupa. Situated in Kathmandu, Nepal, this sacred site holds great significance for Tibetan pilgrims and was constructed around 1650 AD. The stupa is also referred to as Shree Gha-Shanti Ghat Bhajradhatu Mahachaitya.
The central stupa is encircled by smaller chaityas, inscriptions, statues, and an ancient cloister reminiscent of Tibetan monasteries. A statue of Avalokiteshvara is positioned in front of the stupa, adding to its spiritual aura. Kathesimbhu stupa serves as an alternative pilgrimage destination for those unable to visit the Swayambhunath Temple, ensuring that all pilgrims can benefit from its divine presence. Notably, the thirteen steps on the spire symbolize the thirteen stages one must traverse to attain Nirvana.According to mythology, Acharya Vak-vajra of Kwa-baha was requested by the King of Benaras to consecrate a chaitya built in the region. In response, Vak-vajra sprinkled water from the sacred Ganges River over the monument. However, the king doubted his powers. To demonstrate his extraordinary abilities, Vak-vajra entered a state of deep meditation and effortlessly transported the chaitya to its current location in Kathmandu. Another legend suggests that the materials leftover from the construction of the Swayambhunath stupa were utilized to build this magnificent structure.
Historical records mention the stupa in a 1552 AD inscription (Nepal Sambat 762). The inscription reveals that Megharaja, in remembrance of his deceased son, donated the golden pinnacle of the chaitya. He also established a guthi, a religious trust, to conduct annual commemorative rituals. This guthi maintains close ties with the priests of the nearby Kwa-baha region. During the reign of King Pratap Malla (1624-1674 AD), the stupa underwent repairs. In 1647, the chaitya was de-consecrated but was later restored by Vajracharya in 1653, preserving its sanctity and historical significance.
