The Oradea Bishopric Assembly consists of the Oradea Catholic Cathedral and the Bishopric Palace. The bishopric palace was designed by architect Franz Anton Hillebrandt (1762-1770), who also continued the work of the italian architects Giovanni Batista Ricca and Domenico Luchini at the Cathedral (1752). Hillebrand’s design for the bishopric palace (a three storeys U shaped layout) folows the wienese exemple of Belvedere palace, wereas the Cathedral is a merging between the classical design of a three naves basilical space and the “Il Gesu” model with nave and lateral chapels.
