Pisa. Along with Venice and Genoa, it is one of the three great maritime states of northern Italy. Situated near the Tyrhennian Sea in the heart of Tuscany, Pisa is well-poised to exert a grip over not Italy, but, through trade and conquest, the Mediterrananean.
Overview of the city. Slightly updated texturing compared to the other screenshots.
A view of the area of Pisa south of the Arno River. This area should be represented as a Permanent Stone Fort. If one successfully takes the city, then he will spawn in this area. Note that the southern city is not actually on the map, only the cleared area between it and the river is.
A view of the area of Pisa north of the Arno River; the walled area of the city. You can also see the farms and hamlets that dot its outskirts.
A close-up of the walled city itself.
Suggestions for extra content for the city are welcome, personally, I feel that it is a bit bland.
A big thanks to Sutman for his maps, which were of great assistance.
