Denmark consists of the peninsula of Jutland (Jylland) and 405 named islands. Of these, 82 are inhabited, with the largest being Zealand (Sjælland) and Funen (Fyn). The island of Bornholm is located somewhat east of the rest of the country, in the Baltic Sea. Many of the islands are connected by bridges; the Øresund Bridge connects Zealand with Sweden, the Great Belt Bridge connects Funen with Zealand, and the Small Belt Bridge connects Jutland with Funen.

The country is mostly flat with little elevation; the highest natural point is [Ejer Bavnehoej], at 171 metres. The climate is temperate, with mild winters and cool summers. Main cities are the capital Copenhagen (on Zealand), Aarhus, Aalborg (on Jutland) and Odense (on Fyn).
