A great museum! We visited it on the same day as Ephesus, it perfectly complemented the impressions. The cost is 10€ (tour.350 lira). There is an audio guide (we did not take it, so I will not say more precisely in which languages). A souvenir shop with mini versions of the exhibits. I recommend you to visit on occasion.
Since the region is one of the most important settlement areas of ancient civilizations, it has enough artifacts to feed all the archaeological museums in Turkey. Here, too, the majority of the artifacts are artifacts found during the excavations of Ephesus and Artemis. The details in the works are of a kind that a person's mind cannot comprehend. It is impossible not to feel admiration. The museum is passing Cards.
