Church of the Assumption in Postoloprty

The Church of the Assumption is a Baroque church in Postoloprty, a town in the Louny District of the Ústí nad Labem Region in the Czech Republic. The single-nave building stands between the local chateau and the town square and is listed as a cultural monument of the Czech Republic. It remains one of the most recognizable landmarks in town and a lasting trace of a Baroque foundation by the powerful Schwarzenberg family.

Who founded the church, and why was it built?

The church was commissioned by Prince Josef I Adam of Schwarzenberg and his wife, Maria Theresia of Liechtenstein, to fulfill a vow they had made to God. The couple had prayed for a son, and when Jan Nepomuk I of Schwarzenberg was born in July 1742 — later known as the driving force behind the shipping canal that carries the family name — they resolved to honor their promise by building a church. The foundation stone was laid on 13 October 1746 in the presence of both founders.

When was the church built, and who designed it?

Construction ran from 1746 to 1753, based on a design by architect Antonio Altomonte. The resulting church became the Baroque centerpiece of Postoloprty, positioned between the town's chateau and its main square — a layout still easy to trace today when walking from the chateau toward the town center.

What can visitors see inside?

The interior features stucco decoration — volutes and cornices — created by Viennese craftsmen, a sign of the scale and ambition behind the commission. The church holds five altars in total: one main altar and four side altars. The painting on the main altar depicts the Assumption of the Virgin Mary and was created by Viennese painter Michelangelo Unterberger. This canvas gives the church its dedication and remains the visual focal point for anyone stepping inside.

What role does the church play in Postoloprty today?

As the town's deanery church, it serves as the main parish church of Postoloprty and remains an active place of worship. The building takes part in the nationwide Night of Churches event, opening its doors to visitors outside regular service hours so they can get a closer look at its Baroque furnishings and founding history.
