Kudan Stupa, also known as Nigrodharama, is an important archaeological and pilgrimage site located around 4.5 km south of the Sacred Garden in Lumbini, Nepal. This ancient stupa is believed to be the spot where Buddha met his father for the first time after his enlightenment. The site holds significant historical and religious value for Buddhists around the world. According to Buddhist texts, it is at Kudan that Buddha gave sermons to his father, King Suddhodana, and other family members, which eventually led to their spiritual awakening. The design of the stupa incorporates typical Buddhist architecture, with a semi-spherical dome representing the vastness of the universe. Over the years, the structure has undergone several restorations to preserve its sanctity and historical importance. Along with the stupa, there are remains of ancient monasteries and structural complexes, which offer insights into the monastic life during Buddha's time. Visitors to Kudan Stupa can immerse themselves in the tranquility of the place and enhance their understanding of Buddha's life and teachings.
