He also built a three-storied preaching hall and the walls, railings and the moat round the temple. Today Gangaramaya serves not only as a place of Buddhist worship; it is also a centre of learning. The temple is involved in Buddhist welfare work including old peoples' homes, a vocational school and an orphanage. The temple is uniquely attractive and tolerant to congregation members of many different religions. It has also been instrumental in establishing the Buddhist temple on Staten Island (US) the Buddhist Center in New York and the Buddhist Centre in Tanzania, thereby helping to propagate the Dhamma in other countries.
