In my atlas it says the largest european city is Moscow. But when you look for Moscow it is un Russia. Russia is a county of Asia.

I am confused!

Most of Russia is in Asia, but the western part is in Europe.

Check this map. Note that the Ural Mountains divide Europe and Asia.

I understand your confusion. The classification of countries and continents can sometimes be a bit complicated. While it is true that a significant portion of Russia is located in Asia, a part of Russia also extends into Eastern Europe. Moscow, the capital city of Russia, is located in the European part of the country. This is why it is considered a European city.

To determine the largest European city, you can use different criteria such as population or land area. Based on population, Istanbul, the largest city in Turkey, is often considered the largest city in Europe. However, Moscow is also highly populated and can be considered one of the largest cities in Europe as well. These classifications can vary, depending on the specific source or reference used.
