Yogyakarta is a special administrative region in Indonesia. It's the only province in Indonesia that is still headed by a monarchy. Sultan Palace was built in 1756-1790 by Sultan Hamengkubuwono I. Its architecture is the example of Javanese cosmos style and reflects Javanese culture. The Palace is still used as the residence of King or Sultan and also as Javanese art and cultural center.
One of the highlight is to learn the life of 'abdi dalem', people who voluntarily subjugate their service to the Sultan (King). Abdi dalem is an interesting topic to explore. Abdi Dalem aren't just employess at the place. They dedicate their life to the King and become part of the palace itself.
