It’s situated in Yogyakarta, Indonesia. Keraton Ngayogyakarta Hadiningrat is the official local name of the sultan's palace, squarely, at the southern end of Jl Malioboro. It is accessible on foot, by becak, or local cabs.The main palace is on behind the Siti Hinggil Pagelaran. The entrance fee is about Rp15.000 ($2.00) with optional fee of Rp1.000 for bringing a digital or video camera. Guides are also optional and can be hired at the entrance.

The word keraton is an ancient term for the place where the queen lives. There is also another similar word called kedaton which carries the same meaning. In any case, Yogyakarta's keraton (modern spelling has it as "kraton") is dedicated for regency's sultan and definitely not for a queen. The architect of this two-century-old palace complex is the late Sultan Hamengku Buwono I, the founder of the Ngayogyakarta Hadiningrat kingdom. Measuring about 14,000 m² in size, the complex was completed back in 1756 with extensive showcase of Javanese palace architecture.

The palace court with its grand and elegant Javanese architecture lies in the centre of the city. It was founded Prince Mangkubumi in 1755. The Prince was then called Sri Sultan Hamengku Buwono I. He chose the right location of the compound between the Winongo River and the Code River.

The wide-scale of the Palace is from north to south. The front yard is called Alun-alun Utara (the North Square), and the back yard is called Alun-alun Selatan (the South Square). The lay out of the buildings shows that the Palace, the commemorative column and Mount Merapi lie in on line.

The palace meeting hall is called the Pagelaran, where formal meetings of palace officials are held, while the "Manguntur Tangkil" hall is the place where the Sultan is seated.

The palace visitors can enjoy the atmosphere of the kraton in former times by visiting the life-size diorama of wedding ceremonies on the palace meeting, performed by puppets which are intentionally arranged to create such an atmosphere. Sets of Javanese musical instruments, antiques and heirlooms have made the Palace of Yogyakarta.
