This is the Pulo, Molfetta's neolithic site. From the air you can clealy see how it is a round depression in the midst of an otherwise flat territory. You can also see the cave dwellings in the walls and the gunpowder factory in the center. The structure in the bottom right of the photo is the 16th century monastery.
