What city lies in Europe and asia?

A transcontinental country is a country belonging to more than one continent. The definitions used may vary according to which criteria are used (whether purely geographical or, on the other hand, political, economic or cultural criteria). An example is Russia, which has its historical core as well as most of its population (75%), economic activity and political institutions (such as its capital city) in Europe, yet geographically most of the territory (75%) is actually in Asia. By most definitions, Russia straddles both in Eurasia.
