Oradea, formerly known as Nagyvárad, is a city in Romania, located in Crișana. The seat of Bihor County, Oradea is one of the most important economic, social, and cultural centers in the western part of Romania. While modern Oradea is first mentioned in 1113, under the Latin name "Varadinum" in a diploma belonging to Benedictine Zobor Abbey, Bishop Sixtus Varadiensis and Saul de Bychar are mentioned in the document, recent archaeological findings, in and around the city, provide evidence of a more or less continuous habitation since the Neolithic.

Oradea's current architecture is a mix of Communist-era apartment buildings, mainly in the outer quarters, and beautiful historical buildings that are remnants of the era when the city was part of Austria-Hungary. In addition to many Baroque buildings, Oradea is remarkable for its particularly rich collection of Art Nouveau architecture.
