The '''Moon Church''' ({{langx|ro|Biserica cu Lună}}) is a Romanian Orthodox church located at 10 Piața Unirii, Oradea, Romania. It is dedicated to the Dormition of the Mother of God.

==History== The local Orthodox community mainly lived in the Velența and Orașul Nou ('New Town') districts, and was composed of Romanians, Serbs, Aromanians and Greeks. A number of them acquired substantial wealth, were prominent in city life and wished to build a grand church. Two wealthy and influential judges on the appeals court, Püspöky Mihály and Kristoff Mihály<ref name= g>{{in lang|ro}} Laura Gal, [https://adevarul.ro/locale/oradea/cum-fost-ridicata-biserica-luna-cea-mai-cunoscuta-biserica-oradea-1_5ce1912d445219c57ed08597/index.html “Cum a fost ridicată Biserica cu Lună, cea mai cunoscută biserică din Oradea”], ''Adevărul'', May 21, 2019</ref> - noblemen devoted to the Orthodox faith - obtained an audience with Joseph II.

==Description== thumb|Iconostasis of the church The style is late Baroque with clear classicizing elements, as well as a decided provincial stamp. The interior strictly adheres to the norms of Byzantine architecture. <ref name="d"/> The keystone above the iconostasis<ref name="e"/> used to feature a portrait of Vasile Ursu Nicola, better known as the revolt leader Horea and usually considered the only authentic depiction of his face. Today, a copy stands in its stead; the original is at the Oradea Diocese museum.<ref name="d"/>

The nickname derives from a mechanism installed in the spire in 1793. The clock and moon are the work of an innovative Viennese hobby astronomer and clockmaker, Georg Rüppe.<ref name= BcL>{{cite web |title= Biserica cu Lună: Mecanismul orologiu[lui] |website= official website |lang= ro |url= https://www.bisericaculunaoradea.ro/mecanismul-orologiu/ |access-date= 9 December 2025}}</ref><ref name= KnH>{{cite book |title= Reise Know-How Rumänien |year= 2012 |publisher= Reise Know-How Verlag Peter Rump |place= Bielefeld |page= 709 |lang= de |url= https://www.reise-know-how.de/sites/default/files/9783831721757_rf_probe_rumaenien_12.pdf |access-date= 9 December 2025}} Exerpt from tour guide book.</ref> The mechanism that turns the moon is designed to complete a whole rotation around its axis every 28 days, thus indicating the phases of the moon, based on the daily cycle marked by the clock mechanism.
