Esztergom

Esztergom is the most holy town of Hungary. It's where King Istvan (St. Stephen) was crowned as the first christian king of Hungary in 1000 AD. After being destroyed by the invading Mongols and Turks and only gradually rebuilt in the 18th and 19 century, today, the town itself is rather bland. What makes Esztergom worth visiting is the magnificent cathedral. This building dominates the whole town and, located on a hill, can be seen from miles away. The sheer size of it dwarfs every other structure in the surroundings. Thanks to the windows in the immense dome the interior is surprisingly light and airy.

Standing outside the cathedral, you can see Slovakia on the other side of the Danube.
