One of the gem cities of Northern Europe, Tallinn is the capital of Estonia. The city of Tallinn, a major Baltic port, a rail and highway junction, an industrial center, and the largest city of Estonia, is located on the Gulf of Finland, opposite Helsinki, on Estonia's north coast to the Baltic Sea.

Tallinn is divided into eight administrative districts naming Haabersti, Kesklinn, Kristiine, Lasnamäe, Mustamäe, Nõmme, Pirita, and Põhja-Tallinn.

Tallinn has made marvelous development in the information technology sector in recent years. On 13 December, 2005, the New York Times dubbed Estonia as “a sort of Silicon Valley on the Baltic Sea”. Skype is one of the several IT startups under Tallinn’s belt.
