Leaning tower pisa green

The Leaning Tower of Pisa, renowned for its tilt, is one of Italy's most iconic landmarks, set on the Piazza del Duomo surrounded by the green Field of Miracles.

About this subject

The Leaning Tower of Pisa is the bell tower of Pisa Cathedral, located on the Piazza del Duomo, commonly called the Field of Miracles, referring to the green lawn that surrounds it. Construction began in 1173 and continued over 199 years in three phases, interrupted by wars and structural issues. The Romanesque tower stands 55.86 meters tall on the lower side and 56.67 meters on the higher side, with a base diameter of 15.5 meters. Its tilt of about 3.97 degrees (after corrections) is due to unstable clay and sandy soil, which began to settle even during the construction of the second floor. Over centuries, the lean worsened, prompting stabilization efforts, such as soil removal from beneath the north base in the 1990s and the installation of lead counterweights, reducing the tilt by about 0.5 degrees. Today, the tower is safe and open to visitors, attracting millions annually. The contrast between the white marble structure and the green grass of the Field of Miracles creates one of the world's most photographed scenes. The tower houses seven bells, each with a name and musical note, but they have not been rung since the 20th century to avoid vibrations. UNESCO designated the Piazza del Duomo a World Heritage Site in 1987, recognizing the architectural ensemble of tower, cathedral, baptistery, and cemetery.
