April 4, 2011, at Lumbini, Nepal, birthplace of Buddha.
The center has two names: Lumbini Udyana Mahachaitya, and World Center for Peace and Unity. It is designed and guided by H.E. Trungram Gyaltrul Rinpoche, a prominent lineage holder of Karma Kagyu school of Vajrayana Buddhism, and a Harvard PhD.
Built in the UN protected Lumbini Development Project area at the World Heritage Site of Lumbini, the center would represent all the friends and devotees of Buddhism who are not represented by any other temple of center on the project ground, without sectarian bias. You can read more about the overall UN development project at the website of the Lumbini Development Trust.
