Where is the tower of Pisa located and why it was built there?

The Leaning Tower of Pisa is located in Pisa, Italy. It was constructed as the freestanding bell tower for the nearby cathedral, part of the Piazza dei Miracoli complex, which is a UNESCO World Heritage site. Its unique tilt resulted from an unstable foundation built on soft ground, making it a notable architectural and engineering marvel. The tower's construction began in the 12th century and continued for nearly 200 years, reflecting the city's wealth and artistic aspirations during that period.
