|Selçuk - the town
Selçuk stands on a fertile plain of the River Cayster, surrounded by hills, around 3 kilometres (2 miles) northeast of the ancient city of Ephesus. The archaeological site begins between the two hills in the foreground, on the left of the photo.
The road running from the town diagonally to the right side of the photo leads southeast to the site of ancient Magnesia on the Maeander and the modern town of Aydin. In the other direction, the road heads north to Izmir.
The river Marnas, flowing from the southeast, merges with the Selinus south of Selçuk, between the road and the town. The Selinus then merges with the Cayster (Greek, Κάυστρος, Kaystros; Turkish, Küçük Menderes, Small Maeander) in a marshy area to the southwest of the town. The Cayster runs into the Aegean Sea, around 5 kilometres southwest of Selçuk (see photo below).
