Esztergom (known by alternative names) is a city in northern Hungary, about 50 km north-west 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 till the mid-13th century and it was the Royal Seat until King Béla IV of Hungary moved to Visegrád and later to Buda.

Esztergom still is the seat of the prímás (see Primate) of the Roman Catholic Church in Hungary. The city has the Keresztény Múzeum, the largest ecclesiastical collection in Hungary. Its cathedral, Esztergom Basilica is the largest church in Hungary.

One of the newest sights of Esztergom is the Mária Valéria bridge, connecting Esztergom with the city of Štúrovo in Slovakia. Originally it was inaugurated in 1895, but the retreating German troops destroyed it in 1944. It was rebuilt in 2001 with the support of the European Union.
