Tallinn, first mentioned in 1219, received city rights in 1248, but the earliest human settlements date back 5,000 years. The initial claim over the land was laid by the Danes in 1219 after a successful raid of Lyndanisse led by Valdemar II of Denmark, followed by a period of alternating Scandinavian and German rule. Due to its strategic location, the city became a major trade hub, especially from the 14th to the 16th century, when it grew in importance as part of the Hanseatic League.
Tallinn's Old Town is one of the best preserved medieval cities in Europe and is listed as a UNESCO World Heritage Site. Tallinn is the major political, financial, cultural and educational center of Estonia. Often dubbed the Silicon Valley of Europe, it has the highest number of startups per person in Europe and is a birthplace of many international companies, including Skype.
The city will soon house the headquarters of the European Union's IT agency.
Tallinn is already home to the NATO Cybersecurity Center of Excellence cementing its reputation in internet issues. The super popular SKYPE was developed in Tallinn.
