Last Monday, we went for a school trip. We visited a small museum in the south of Poland. The museum used to be a mansion of a famous family who lived there in the 19th century. The family helped all the nearby villages develop by opening mines and factories. They became so rich because they had invested a huge amount of money in gold bullion. They bought the bullion from a famous North American investor when they visited the United States in 1834. Then they hid the gold in their suitcases, which was quite risky, and travelled through the continent and then across the ocean to Poland, where they bought the mansion. A couple of years later, they sold some of the bullion bars and got a huge amount of money. Gold must have been really expensive then because only two months later, they opened their first mine in the nearest town. The mine was named after one of the family members. It gave jobs to lots of people who had been unemployed for a longer period of time. Some time later, they sold more bullion. A factory and a tailoring company were opened in another town. Those plants gave work to hundreds of people. Unfortunately, the family left the country during the First World War and nobody knows if they survived, but the mine and the factories are still working and lots of people can earn money only because they have jobs there.
