[2] Under his rule, Ambarrukmo Palace was made the primary meeting point between the royal families of Yogyakarta and Surakarta.

[6] In 1940, the palace complex was temporarily repurposed as the Police Inspector Academy of the Republic of Indonesia, before later becoming the seat of the Government of Sleman, during Regent Pringgodiningrat's term.

[7] In 1957, under the instructions of President Sukarno and Hamengkubuwono IX, construction started on the hotel, located within the complex, east of the palace building.

[15] Much of the former Ambarrukmo Palace was built in a traditional Javanese style, and features a Pendopo Agung, Ndalem Ageng, Bale Kambang, Gandhok, Pacaosan and an Alun-Alun, each of them once serving a specific function for the royal family.

[7] The Bale Kambang, located towards the back of the compound, is unique amongst the palace's buildings due to being built with a fusion of Dutch and Javanese architecture.

[17] Apart from the buildings of the former palace, the hotel also houses several artworks commissioned in the 1960s by local artists, including two large mosaic murals telling the story of the life of Yogyakartans and Javans.
