The Gunongan (MAHS-IND-ACH-BNA-S-001-F-0001) is one of the few surviving structures from the former palace grounds of the Aceh Sultanate. It is an open structure building with ten sides, and has three levels. This massive building is built of stone, sand, brick, and lime mortar. The entrance building is oriented toward the southwest. The base of every exterior corner is ornamented with a single large trefoil design. Floral ornamentation is also found on the corners of the upper level, featuring an Acehnese pucok reubong motif.
