Slovakia's position in Europe and the country's past (part of the Kingdom of Hungary, the Habsburg monarchy and Czechoslovakia) made many cities and towns similar to the cities in the Czech Republic (such as Prague), Austria (such as Salzburg) or Hungary (such as Budapest). A historical centre with at least one square has been preserved in many towns. Large historical centers can be found in Bratislava, Trenčín, Košice, Banská Štiavnica, Levoča, and Trnava. Historical centres have been going through a restoration in recent years.
