The site went into decline at the end of the Mycenaean period, and was completely deserted by the time Pausanias visited in the 2nd century AD. This site was excavated by Heinrich Schliemann in 1884–1885, and is the subject of ongoing excavations by the German Archaeological Institute at Athens and the University of Heidelberg. In 1300 BC the citadel and lower town had a population of 10,000 people covering 20–25 hectares. Despite the destruction of the palace in 1200 BC, the city population continued to increase and by 1150 BC it had a population of 15,000 people.
