The ìMarinella Projectî was developed within the territory of the Magra Valley and has very unique natural, landscape and historical features. The first historiographic news regard the foundation of the city of Luni which, although at first used as a military port, then developed and became a dock used for the marble trade (today known worldwide as ìCarrara marbleî). The city had 10,000 inhabitants and still today the signs of its thriving Roman period can be admired in the archaeological site of Luni. The two Roman walls date back to this period: the first in the territory bordering the city of Luni is marked by a narrow and regular grid and a layout which reflects the road system inside the city and the city walls; the second spreads over a larger territory and has a square grid with a side of 720 meters. The land divisions found in Luni also affect the bordering towns, from Sarzana up to Pietrasanta, thus providing evidence still today of the main role played by Luni on this territory.
