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.
