The main part of Denmark proper is Jutland, a peninsula north of Germany, but Denmark also includes a great number of islands, of which the major ones are Zealand and Funen.
Most of the islands are situated in the small shallow sea of Kattegat and the Baltic Sea, between Jutland and Sweden. Separated from the other islands, Bornholm lies by itself between Sweden and Poland in the Baltic Sea. The capital, Copenhagen, is located at the most eastern side of Zealand. Once the seat of Viking raiders and later a major north European naval power, The Kingdom of Denmark is the oldest kingdom in the world, but has evolved into a democratic, parliamentary, modern and prosperous nation. The country is participating in the general political and economic integration of Europe. However, the country has opted out of the European Union's Maastricht Treaty, the European monetary union. Denmark is the birthplace of one of the world's most popular toys, Lego, and boasts the Legoland theme park in Billund.
