A view of St. Thomas Hill and the Chapel from the Castle. They are really close to each other, so it's worth to visit both.
The hill was named after the martyr archbishop of Canterbury, Thomas Becket. The original church on the hill was built by Margaret Capet, daughter-in-law of Henry II whose knights assassinated Becket. The widowed Margaret later married the Hungarian king Bela III.
Though you cannot really go very off the beaten path in Esztergom, I think most visitors only come for a day and only visit the Cathedral and the Castle Hill, so I decided to put St. Thomas Chapel in this category.
The classicist chapel on St. Thomas Hill was built in 1823. The view from here is very nice, you can see both the Basilica and Sturovo on the Slovakian side of the River Danube. As you are climbing up the hill, you can see the baroque Stations of the Cross.
