Today, it runs with the local government of the Nepalese republic, established in 2015, and is part of the Lumbini Province.

Nearby tourist attractions
The Ramagrama stupa is a stupa located in Ramgram Municipality, about 11 km from Sunwal. This Buddhist pilgrimage site, which was constructed around 2500 BCE, contains relics of Gautama Buddha. According to Buddhist texts, after Buddha's Mahaparinirvana, his cremated remains were divided and distributed among the princes of eight of the 16 mahājanapadās. Each of the princes constructed a stupa at or near his capital city, within which the respective portion of the ashes was enshrined. One of them was Rāmagrāma, a major city of the Koliya kingdom (sometimes referred to as Koliyanagara) at that time.

As of today, the Ramagrama stupa is the only intact and original stupa which contains relics of Buddha. The 7 m high stupa is now buried under a mound of earth and is awaiting further research.
