The plain is the largest agricultural area on any of the Adriatic islands, and is remarkably fertile due to Ice Age loess deposition.

[5] The colonists divided the plain into 75 land parcels (called chora), each measuring roughly 16 hectares, bordered by dry stone walls.

[1] The original field layout has been respected by the continuous maintenance of the boundary walls by succeeding generations.

In addition to the chora, the Greeks built small store huts made of dry stone called trims, where tools were kept and people could take refuge from bad weather.

[1] Large storage cisterns and gutters were also built throughout the plain to retain rainwater, to handle the dry Mediterranean climate.
