Giambattista Nolli (1701-1756) was an Italian architect and surveyor. He is best known for his plan of Rome, the "Pianta Grande di Roma", began in 1736 and concluded in 1748. The map is composed in 12 tiles, and its measure is 176 x 208 cm. It was by far the most accurate description of Rome produced at that time.
