Santa María

The Piazza del Duomo ("Cathedral Square") is a wide, walled area to the north of central Pisa, Tuscany, Italy, recognized as one of the main centers for medieval art in the world. It is a sacred area, Catholic Christian religion, and it is dominated by four great sacred edifices: the Duomo (cathedral), the Campanile (the cathedral's free standing bell tower), the Baptistry and the Campo Santo (the monumental graveyard). Partly paved and partly grassed, it hosts also other buildings such as the old hospital (now in part the Museum of Sinopias) and the Museum of the "Opera del Duomo" (the Cathedral Square museum]. It is otherwise known as Piazza dei Miracoli ("Square of Miracles").

The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply the Tower of Pisa (Torre di Pisa) is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa, known worldwide for its unintended tilt to one side. It is situated behind the Cathedral and is the third oldest structure in Pisa's Cathedral Square (Piazza del Duomo) after the Cathedral and the Baptistry. The tower's tilt began during construction, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt increased in the decades before the structure was completed, and gradually increased until the structure was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries. The height of the tower is 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side. The width of the walls at the base is 2.44 m (8 ft 0.06 in). Its weight is estimated at 14,500 metric tons (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. Prior to restoration work performed between 1990 and 2001, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees. This means that the top of the tower is displaced horizontally 3.9 metres (12 ft 10 in) from where it would be if the structure were perfectly vertical.

La torre di Pisa (popolarmente torre pendente e, a Pisa, la Torre) è il campanile della cattedrale di Santa Maria Assunta, nella celeberrima piazza del Duomo di cui è il monumento più famoso per via della caratteristica pendenza, simbolo di Pisa e fra i simboli iconici d'Italia. Si tratta di un campanile a sé stante alto 57 metri (58,36 metri considerando il piano di fondazione)[1] costruito nell'arco di due secoli, tra il dodicesimo e il quattordicesimo secolo. Con una massa di 14.453 tonnellate,[1][2] vi predomina la linea curva, con giri di arcate cieche e sei piani di loggette. La pendenza è dovuta a un cedimento del terreno sottostante verificatosi già nelle prime fasi della costruzione.

L'inclinazione dell'edificio misura 3,9° rispetto all'asse verticale.[3] La torre è gestita dall'Opera della Primaziale Pisana,[4] ente che gestisce tutti i monumenti della piazza del Duomo di Pisa. È stata proposta come una delle sette meraviglie del mondo moderno.
