Giambattista Nolli (or Giovanni Battista, April 9, 1701 – July 1, 1756) was an Italian architect and surveyor. He is best known for his ichnographic plan of Rome, the Pianta Grande di Roma which he began surveying in 1736 and engraved in 1748, and now universally known as the Nolli Map. The map is composed of 12 copper plate engravings that together measures 176 centimetres (69 in) by 208 centimetres (82 in) and was published in response to the commission of Pope Benedict XIV to survey Rome in order to help create demarcations for the 14 traditional rioni or districts. It was by far the most accurate description of Rome produced to date at a time when the architectural achievement of the Papacy was in full flower.
The Nolli map reflects Bufalini's map of 1551, with which Nolli readily invited comparison, however Nolli made a number of important innovations. Firstly, Nolli reorients the city from east (which was conventional at the time) to magnetic north, reflecting Nolli's reliance on the compass to get a bearing on the city's topography. Secondly, though he follows Bufalini in using a figure-ground representation of built space with blocks and building shaded in a dark poché, Nolli represents enclosed public spaces such as the colonnades in St. Peter's Square and the Pantheon as open civic spaces. Finally, the map was a significant improvement in accuracy, even noting the asymmetry of the Spanish Steps. The map was used in government planning for the city of Rome until the 1970s; it was used as a base map for all Roman mapping and planning up to that date.
The map is framed with a vedute by Stefano Pozzi. A scaled-down edition, a collaboration between Nolli and Giovanni Battista Piranesi, was published in the same year the original map was finished. Piranesi was instrumental in getting the work printed; Giuseppe Vasi also contributed.
