The discoveries of archaeological sites scattered only a few miles away suggested that this area was once an important religious, political, and urban center of central Java.
[3] In 2012, the Balai Pelestarian Peninggalan Purbakala Jawa Tengah (BP3, or the Central Java Heritage Preservation Authority) suggested that the area in and around Prambanan should be treated as a sanctuary.
This was meant to protect this archaeologically rich area from modern-day visual obstructions and the encroachments of hotels, restaurants, and any tourism-related buildings and businesses.
