Esztergom (Hungarian pronunciation: [ˈɛstɛrɡom] ; German: Gran; Latin: Solva or Strigonium; Slovak: Ostrihom, known by alternative names) is a city with county rights in northern Hungary, 46 kilometres (29 miles) northwest of the capital Budapest. It lies in Komárom-Esztergom County, on the right bank of the river Danube, which forms the border with Slovakia there. Esztergom was the capital of Hungary from the 10th until the mid-13th century when King Béla IV of Hungary moved the royal seat to Buda.
