At about 350 BCE, Priene is believed to have been rebuilt. It was not a harbor city any more, and its outlet to the sea was secured by the port of Naulochos. The city was built in concordance with the “grid system” developed by architect Hippodamus of Miletus.
From north to south after the excavations the streets named as Athena Street, Theatre Street and Source Gate Street and main street of West Gate Street. Temples, agorae, gymnasiums, bouleuterion etc. were situated in the central part of the town, were open to the public.
One of the three gates of the city was in the west, and the other two are in the east. The East Gate was the main gate of Priene, situated to the north east of Theatre Street. The west Gate opens onto the widest street of Priene.
The city provided the water from the sources of Mycale. The aqueducts brought the water to the reservoirs, located in the north east of the city. It was distributed to the all city by many fountains.
