Priene is an Ancient Greek city. It is believed to be the pinnacle of the Greek grid city planning. Its closed-grid structure reveals main the ideals of the Greek grid, which became a popular tool in founding colonies. Firstly, as victorious Greeks brought democracy to the conquered lands, they established towns with lots of equal sizes: Priene consisted of bigger public spaces and 80 equal blocks with 5 private houses each. Secondly, Greeks were focused on occupying strategically important locations that provided good viewability and protection: Priene was built on the slope of the Mycale mountain and overviewed a port of the Aegean Sea. The combination of the steep slope and the gridiron plan provided great visibility of the port and the city itself.
