Industries include metalworking, machinery, textiles, ceramics, glass, chemistry, sugar making, etc. It also produces marble and alabaster carvings. Railway and highway hubs. There is the University of Pisa (founded in 1343). Multi-medieval architectural art. The famous Leaning Tower of Pisa (the tower body is inclined due to careless foundation) is about 55 meters high and the diameter of the tower bottom is 15.24 meters. Built in 1 174- 1350. At present, the south inclination angle of the tower top has exceeded the vertical plane by 5.3 meters, with an inclination angle of 5 6'. Galileo once did the famous leaning tower experiment here. There are also Roman cathedrals, museums and libraries. Tourism is developed. A mining city in southwestern Montana. Located in the Rocky Mountains. The population is 37,000 (1980). It was built after the discovery of gold in 1864. 1882 changed to copper mining, which made great development.

Pisa, located in the northwest of Florence, is a seaside city in history. With the expansion of land, Pisa is farther and farther away from the sea, but this can't make people forget the history of Pisa as an important town of ocean and national prestige and its important role as a link between East and West. In addition, because of its history and architectural art, Pisa has become a famous tourist city today.
Leaning Tower of Pisa
The reputation of Pisa is largely due to the Leaning Tower of Pisa. The tower was completed on 1350, but the project started earlier than 1 174. At that time, when the project went to the third floor, it was found that the tower was tilted due to the foundation and building structure. So the project was interrupted. Later, the incumbent changed and a new architect was hired to continue the project.
With the passage of time, the inclination of the leaning tower of Pisa has been increasing, reaching 4.5 meters at present, and the inclination continues to increase at the rate of 1 mm per year.
Perhaps it is precisely because of its inclination and uniqueness that its reputation has become "crooked", growing bigger and bigger, with an endless stream of visitors.
