Astana Giribangun, Mausoleum complex in Karanganyar, Indonesia.

Astana Giribangun is a mausoleum in Karanganyar on Java, set within forested hills east of Surakarta. The compound displays stone walls, carved gateways, and roofs in Javanese style, surrounded by maintained paths and trees.

Astana Giribangun was built in 1974 by the Mangadeg Foundation and inaugurated on 23 July 1976, when the remains of K.P.H. Soemoharjomo and Siti Hartini Oudang were moved here from Utoroloyo cemetery in Surakarta. Suharto was buried beside his wife Tien on 29 January 2008 with full military honours, President Susilo Bambang Yudhoyono presiding. In October 2010 the family held a memorial ceremony here 1,000 days after his death.

The Javanese name means "Palace of the risen mountain", referring to the site on the slope of Mount Lawu. The burial halls are joglo-style pavilions with Surakarta-style carved wooden walls and sirap (wooden shingle) roofs. The three tiered cungkup are named Argo Sari, Argo Kembang and Argo Tuwuh, and the main door faces north.

The site lies roughly 35 kilometers east of Surakarta and is reached by roads winding through the hills. Visitors should wear modest clothing and move quietly, since this remains an active burial ground.

The height of the structure was deliberately limited to respect hierarchy in relation to the nearby royal tomb Astana Mangadeg. This decision follows rules of courtly etiquette that remain visible in the architecture today.
