Frankfurt is the largest city in the region of Hessen in Germany. It is located on the river Main. It is known as the commercial and business center, because here are the European Central Bank, the Federal Bank of Germany and Frankfurt stock exchange. However, the city is primarily interesting by the Gothic buildings. For example, St. Bartholomew's Cathedral is the main religious building of Frankfurt, where the rulers of the Holy Roman Empire were elected, and later the monarchs were crowned there. The first German Parliament with the democratic election was also in this village, it was in St. Paul's Church.
