Hundreds of years ago, salt mining was extremely difficult.

The working conditions of the miners were very difficult, with axes and pickaxes in one hand, oil lamps in the other, and 40 kilograms of salt on their backs, crawling hand and foot in the dark, cramped, stuffy mines, and risking landslides and gas explosions.

There are many wax figures of miners in the tunnels and caves, some of them are climbing, some are carrying rock salt, and some are turning the winch, reflecting the hardships of labor in those years.

Ye Chao was also surprised to see the specimens of several horses.

A horse is pulling a salt cart, and a miner is washing the horse......

Salt mines have had horses working since ancient times, used to transport salt, drag lifts, etc.

So, how did the horse get down the shaft? It is said that the horse was hoisted into a mine more than 100 meters deep with four legs tied. Since going down the well is a "terrible experience" for horses, they don't go up again after they come down.

Usually there are stables in the mines for them to rest, special people to take care of them, and forage is transported underground. Wieliczka's last horse, worked until her retirement in 2002.

Salt carvings are a major feature of Wieliczka.

In the subsequent mining caves one after another, Ye Chao, who was bold in playing, saw many sculptures. According to reports, for hundreds of years, miners like to carve things out of hard rock salt in addition to work. Gradually, salt carving became a major feature of Wieliczka......

The Wieliczka Salt Mine, located on the outskirts of Krakow, has been mined since the 13th century and is still being excavated today, making it one of the oldest and still mined salt mines in Europe.

There are many works of art, altars and statues carved out of salt.

The Wieliczka salt mine is the result of the art of labor in the Middle Ages. From the 14th century, the Wieliczka salt mine became one of the mining cities, the 15th~16th century was the heyday, and in the 18th~19th century, the salt mine began to expand, becoming the famous salt capital of Poland.

In 1976 it was listed as a national monument in Poland, and in 1978 it was designated as a World Heritage Site by the United Nations.

The salt deposit is 4 kilometers long, 1.5 kilometers wide, 300~400 meters thick, and the total length of the roadway is more than 300 kilometers.

In order to facilitate inspections and visits, a staircase was built in the mine as early as 1744.

On the salt road, which is more than 130 meters deep above the ground, it is one of the world's rare tourist attractions.

There is a museum, an entertainment hall, and the original salt lake, prayer hall and miners' labor scene have been preserved. There are many statues and ornaments inside, all carved from salt. Notable sculptures include Leonardo da Vinci's The Last Supper.

The salt mine is not only accessible to tourists, but also to patients with certain diseases. In 1964, a sanatorium for the study of allergic diseases was opened at a depth of 211 meters in the 5th mining area of the salt mine, and in 1974 a sanatorium was built under the mine for patients with respiratory diseases.

"Salt Capital" so the city is called Krakow.

Krakow is the capital of the province of Krakow, a municipality directly under the central government. It is located on both banks of the upper Vistula River. Founded around 700 years ago, it is one of the oldest cities in Central Europe and is home to the Vistula people.

In 1320~1609, it was the capital of Poland, so it was also called the old capital.

Krakow has always been one of the main centers of Polish academics, cultural and artistic life, and is one of the most important economic centers in Poland.

It is considered one of the most beautiful cities in Europe.

In 2000, Krakow was named the European Capital of Culture, and the city will also host the next World Youth Day 2016.

Krakow is the third largest city in Poland and the historical capital of Poland.

During the Renaissance, Poland was the most prosperous and powerful country in eastern Europe. Thanks to its access to advanced knowledge of Mongolian and Central Plains culture from Lithuania and Russia, Poland maintained its reputation as the most advanced country in Europe for a long time.

Krakow, on the other hand, is the center of European culture and science. The famous astronomer Nicolaus Copernicus was educated at the University of Krakow.

It was a Vistula castle until the 10th century. The famous Congress of Gnezhnov, held in 1000, decided to establish the Diocese of Krakow. In 1138 Desław established the Grand Duchy. The Tatar invasion was destroyed in the 13th century.

In 1320 Vladislav reunited Poland and made it its capital. Over the next 300 years, it flourished rapidly and became one of the famous cultural centers of Europe at that time

In 1795~1809 and 1846~1918, it was ruled by Austria twice, and in 1918, it belonged to Poland. During the German occupation in World War II, the entire faculty of Jagiellonian University (the oldest university in Poland, founded in 1363) was killed, and 55,000 Jews were deported to concentration camps.

It was rebuilt after the war and became the third largest industrial city in Poland.

It is now a water and land transportation hub and an industrial center.

The iron and steel industry is particularly important, and there is the largest iron and steel complex in the country, "Lenin Iron and Steel Plant", which has an annual output of 6 million tons of steel and other metallurgical products.

Industries such as coking chemicals, building materials (cement, refractory materials, and prefabricated reinforced concrete), machinery (rolling stock, agricultural machinery), and food processing are also well developed. Second only to Warsaw, it is a cultural and educational center with a long history (founded in 1364), a polytechnic university, an art school, a research institute of mining and metallurgy, and a research institute of atomic physics.

There are 11 higher education institutions in the city, of which the Jagiellonian University is the most famous.

There are observatories, museums, and monuments such as the Palazzo Väwel (which houses treasures of ancient art), castles and churches (there are more than 60 famous ancient churches).

There are textile, food processing, chemical, stone-cutting, metallurgical and other industries, and Xinhuta in the eastern suburbs of the city has the largest iron and steel complex in the country.

An important railway junction in southern Poland. There are many historic buildings in the city, and since 1966 international art exhibitions have been held in the area.

Before the German occupation of Poland, Krakow was one of the earliest and most open regions on the European continent to Jews. As early as the 15th century, Casimir the Great issued an edict allowing Jews to do business in Krakow.

After that, the genius minds of the Jews made great efforts for the development of Krakow's economy.

Krakow is the most important economic center of Poland and the economic center of the Lesser Poland (Little Poland) region. With the collapse of communism, the private sector has been growing steadily. There are about 50 large multinationals in the city, including Google, IBM, Motorola, Delphi, MAN SE, General Electric, Aon Hewitt, Hitachi, Philip Morris, Capgemini, and Sabre Holdings, as well as other British, German and Scandinavian-based companies.
