The Amitabha Foundation Retreat Center is presently being built on a mountain top in Kopan, located approximately 8 km from Boudhanath Great Stupa, in the Kathmandu Valley in Nepal. It will be open to Buddhist practitioners of all paths.
The main structure is built upon the highest point on the hill, designed like a mandala. This, as well as the registered name of Amitabha Foundation, is the reason for the retreat center’s special name “Opak Kyilkhor Chöling” (The Amitabha Mandala Dharma Center). Within the retreat center, there will be a total of sixteen temples both large and small.
