Gdynia is a city in the Pomeranian Voivodeship of Poland and an important seaport of Gdańsk Bay on the south coast of the Baltic Sea. Gdynia, together with nearby Gdańsk and Sopot are often referred as Tricity (pl: Trójmiasto). Gdynia was first mentioned in the 13th century as a fishing village. Its career began after World War I, when it became Poland´s main harbour and the big sea port at the Baltic Sea, which it still is. Gdynia is one of the youngest and modern cities in Poland. In the early 1900s it was a little village, but after WW1 and establishing the Free City of Gdańsk, the Polish Government decided to build a deep-sea port. Construction began in 1921. The city rose fast in the 1920s and 1930s, so architecture and planning reflect European trends of the day - Modernism. The city continues to grow to this day. Today, Gdynia is a modern city with a population of a quarter-million and is the second major polish port in the Baltic Sea after Gdansk.
Stockholm - Sweden's capital and largest city, and the most populous city in the Nordic region. Without a doubt, Stockholm is one of the most beautiful cities in Europe. The city is made up of 14 islands connected by some 50 bridges on Lake Mälaren, which flows into the brackish Baltic Sea, and passes the Stockholm archipelago with some 24,000 islands and islets. The city is a cosmopolitan place with both classical and modern architecture, and a captivating Old Town, Gamla Stan. Today, the area is an atmospheric mixture of buildings surrounded on all sides by a latticework of medieval lanes and alleyways.
Helsinki is the capital and largest city in Finland. Finland's major political, educational, financial, cultural, and research center as well as one of northern Europe's major cities, Helsinki was ranked the most liveable city in the world, in 2011. Approximately 75% of foreign companies operating in Finland have settled in the Helsinki region. The nearby municipality of Vantaa is the location of Helsinki Airport, with frequent service to various destinations in Europe and Asia. Today, Helsinki pulls off the trick of being something of an international metropolis while still retaining a small-town feel. The best time to visit is in summer, when Finns peel off their overcoats and flock to outdoor bars and cafes to enjoy the sunshine.
Copenhagen is the capital and largest city of Denmark. This "friendly old girl of a town" is big enough to be a metropolis with shopping, culture and nightlife par excellence, yet still small enough to be intimate, safe and easy to navigate. Overlooking the Øresund strait with Sweden just minutes away, it is a cultural and geographic link between mainland Europe and Scandinavia. This is where old fairy tales blend with flashy new architecture and world-class design; where warm jazz mixes with cold electronica from Copenhagen's basements. You'll feel you've seen it all in a day, but could keep on discovering more for months. Copenhagen is considered a very liveable place because of its cleanliness. It’s considered as one of the very environmentally friendly cities because its harbour can be swum in and about a third of the city’s people use bicycles as their means of transportation. In their downtown area, the places to visit and to be entertained at are the Tivoli gardens and the Town Hall Square. If you want the very cultural and scenic areas the places to see are the Marble church, the Rosenborg castle, and the Christiansborg.
