Piazza del Duomo, Italy

Home to the leaning tower of Pisa 

Expedition Overview
In February 2005 and July 2006, teams from the Development of Integrated Automatic Procedures for the Restoration of Monuments (DIAPReM) from the University of Ferrara, the Institute of Science and Information Technology of the National Research Council in Pisa and the Department of Architectural Design at the University of Florence conducted a High Definition Survey of the Piazza del Duomo. The data was acquired from 30 positions and was focused on the exterior parts of the Cathedral, the Campanile and the Baptistery. The 3D survey was coordinated and georeferenced with a topographical survey conducted by the DIAPReM team. The final 3D laser scan survey data was registered within the topographic survey with an average error of 3mm and fused into a master dataset (point cloud) that contains a total of 256,653,388 points.
Introducing the Piazza del Duomo
Pisa's Piazza del Duomo, also known as Piazza dei Miracoli (Square of Miracles) is located north of the Arno river and measures nearly nine square hectares. Unlike the paved piazza's typical of Italy, the Piazza del Duomo is an expansive green grassy field dominated by four monumental works of architecture in luminous dressed stone and white marble. The site is made up of the renowned cathedral, baptistery, campanile, and monumental cemetery which provides an edge on the north side of the site.Built over the 11th, 12th and 13th centuries, their existence as four individual entities is typical of Italian architectural practice of this era. 
Campanile
The campanile, known better as the Leaning Tower of Pisa, with its infamous inclination is the one of the most well known monuments in the world, but the history of its construction is less well known. Inscriptions from the base near the door indicated that it was founded in 1173. As the tower has been leaning since shortly after its initial construction due to unstable substrate soils, numerous attempts at reconstruction and stabilization of the campanile in the succeeding centuries have been made. The circular shape and great height (currently 55.86 m on the lowest side and 56.70 m on the highest) of the campanile were unusual for their time, and the crowning belfry is stylistically distinct from the rest of the construction.
