1. The Leaning Tower of Pisa is inclined due to the soft soil layer beneath its foundation.
2. Construction of the tower began in 1174 and was completed in 1350, entirely built from marble.
3. The tower developed a tilt at the third level during construction, which was attributed to the inadequate depth of the foundation and the insufficient strength of the vertical upper structure. As a result, the construction was halted.
4. Ninety-four years later, the project was restarted with measures taken to prevent further tilting.
5. After weathering over 600 years, the Leaning Tower of Pisa remains standing, its distinctive tilt making it globally renowned.
6. The Leaning Tower of Pisa stands on the Piazza dei Miracoli in Pisa, Italy, as an independent bell tower of the cathedral. It was designed by the famous architect Nino Pisano in August 1173 and construction began thereafter.
7. From its foundation to the top, the Leaning Tower of Pisa reaches a height of 58.36 meters. Its bold circular architectural design showcases its innovation. The first tilt occurred in 1174.
8. The Leaning Tower of Pisa was listed as a World Heritage Site by the UNESCO World Heritage Committee at its 11th session.详情
