Why should the Millennium salt mine, which has stored more than 3 billion tons of salt, be transformed into a park to open to the outside world?

First, I think it was driven by interests, so it was transformed into a park. Because the benefits of salt mines are not particularly great, and many salt merchants come here to mine, his income is not particularly ideal, so transforming this eye socket into a park will make his income higher and attract many foreign tourists.

Second, this thousand-year-old salt mine is Natour Salt Mine in Surrey. It has a very long history, dating back to ancient Rome. At that time, the rich salt resources of this salt mine were exploited by colonists, so some people continued to mine and sold the mined salt to all parts of Europe. Therefore, everyone's use of this salt mine is not particularly valuable, so their country has transformed this salt mine into a park, which is also helpful to the country's income.

Third, the Natour Salt Mine Museum in Sally, its tunnel is complicated, and the history of this salt mine is particularly long, which should be 1000 years old. After people's excavation, this tunnel is more than 20 meters wide and 18 meters high, with a particularly large space, which can accommodate more than 3,000 tourists. For example, there are children's areas and many areas.

Salina Turda Salt Mine Museum has attracted more than one million foreign tourists since it was transformed into a park at 1992. It can be seen that this salt mine has brought them a high income.
