Želiezovce (Hungarian: Zselíz, until 1895: Zseliz; German: Zelis) is a town in Slovakia in the Nitra Region in the Levice District, near the Hron river.

The building has been richly decorated with at least four different layers of wall painting, which survive from the late fourteenth and early fifteenth centuries.

The original context of these murals has been analysed in detail in the recent monograph (2018) by Krisztina Ilko, "The Medieval Wall Paintings of the Church of St James in Želiezovce.

"[7] Ilko has investigated how the wall paintings were connected to the patronage of the Becsei family who intended to develop a new dynastic seat in Želiezovce.

The focal point of this research was the unique iconography of a fresco from the 1380s in the apse which depicts a celestial trial for the departing soul of the local landlord and knight George Becsei.
