The central axis of Yogyakarta was established in the 18th century by Sultan Mangkubumi, and has continued from that time as a centre of government and Javanese cultural traditions. The six kilometers north-south axis is positioned to link Mount Merapi and the Indian Ocean, with the Kraton (palace) at its centre, and key cultural monuments lining the axis to the north and south that are connected through rituals. It embodies key beliefs about the cosmos in Javanese culture, including the marking of the cycles of life.
