Košice is a city in eastern Slovakia. It is situated on the Hornád River at the eastern reaches of the Slovak Ore Mountains, near the borders with Hungary. With a population of nearly 236,000 Košice is the second largest city after Bratislava. The first written reference to Košice comes only from 1230, but as the first city in Europe, Košice received its own coat of arms in 1369 from Luis the Great. Its streets are stacked with wonderful monuments and palaces; its cultural scene is spirited and innovative; and official city literature boasts of ten national minority groups that call Košice home. At the centre of Košice is a large pedestrian zone. Along the edges are a number of shops, interspersed with Neoclassical and Baroque palaces, beautifully restored and now housing museums, galleries and offices behind their spectacular facades. Dominante of the square, is the peerless St Elizabeth's cathedral, a staggeringly beautiful Gothic construction. Košice is knowen by Košice's State Theatre, which include the park and illuminated "singing fountain". There is also Východoslovenské Múzem, the Eastern Slovak Museum, the Slovak Technical Museum, the museum dedicated to the Hungarian novelist Sándor Márai. Košice has blossomed in the past 50 years into one of the most attractive cities in central Europe, drawing on a number of influences for its current progress and prosperity. It is also known as the city of youth, where the average age of its population is just 35. Being the economic and cultural centre of eastern Slovakia, Košice is the seat of the Košice Region and Košice Self-governing Region, the Slovak Constitutional Court, three universities, various dioceses, and other institutions.
