Priene
One of the first Ionian cities to have been built around 350 B.C. and fortified according to the plans of Hippodamus (square angled streets on a North-South axis to ensure agreeable aeration).
Priene has in fact never played an important role. By the with-drawing of the sea, she lost all of her small importance. Though, during the Byzantine era, she became an important Diocesan (religious) center.

Miletos
As first but also most important Ionian city, Miletos used to count four harbors. As for Priene, the distance between town and sea becoming bigger due to the drying out of the Meander river, Miletos lost of its commercial interest.
The site is today visited for its amphitheater, nympheum, thermae and a well-preserved Selçuk mosque.
N.B. : The Miletos alphabet is nothing more that the grandfather of our current Latin alphabet.

Didyma
The Sacred Road starting in Miletos was following the coast till Didyma and was lounged by lion statues. The temple counted 112 columns and is the third biggest temple dedicated to Apollo.
