摘要：Many experts have written about the history of the Demak kingdom, therefore the role of this kingdom in politics, economics and especially in the spread of Islam in Indonesia in the past. With the geophysiographical, historical and archaeological approach used in this study, it can be revealed about the environmental conditions and the location of the palace and the royal city of Demak. The research methods used in this research are observation, geophysiographical (drilling, geoelectrical measurement), historical (reading of documents) and archaeological (test pit excavations) methods, to obtain credible conclusions. The result is that the kingdom, which has a fairly large influence in the archipelago, is located on the island of Demak between Java and the Muria peninsula, which is still in a separate condition, which is surrounded by swamps, rivers and the sea. the tombs of kings, the names of places/villages (toponyms), have proven that the existence of the central city of the kingdom is concentrically arranged and the settlement patterns are grouped according to position, profession, ethnicity and religion.
