 Excavations at Miletus , southwest Asia Minor , indicate the existence of a Mycenaean settlement there already from c . 1450 BC , replacing the previous Minoan installations . This site became a sizable and prosperous Mycenaean center until the 12th century BC . Apart from the archaeological evidence , this is also attested in Hittite records , which indicate that <unk> ( <unk> in Hittite ) was the most important base for Mycenaean activity in Asia Minor . Mycenaean presence also reached the adjacent sites of <unk> and Ephesus .
