The Baroque Palace of Oradea (), also known as the Roman Catholic Episcopal Palace of Oradea (), of the city of Oradea in Bihor County, Romania, is a building that dates to the Baroque times. History It was founded in 1762 by the Baron Bishop Adam Patačić, as bishopric palace of the Roman Catholic Diocese of Magnovaradimum. Illustrious Viennese architect Franz Anton Hillebrandt, designer of many Austrian palaces and one of Europe's 18th century best, designed the palace and planned the city's posh side as Baroque quarter, while engineer A.J. Neumann was in charge of the palace's massive construction, complete with its 365 exterior windows resembling the days of the year and 120 large, extravagant rooms distributed on three floor plans. The architecture of the palace is of late Austrian Baroque style, a more sober and practical type compared to the overly ornamented French Baroque, for example. The building was meant to resemble on a smaller scale the famous Royal Belvedere (palace) of Vienna, which likely was one of the reasons along with other religious conflicts that made Empress Maria Theresa of Austria repudiate the founder, Adam Patachich, a Croatian nobleman and the bishop of Oradea between 1759 and 1776; he was then sent to another diocese, in Kalocsa, Hungary.

The bishop also employed at the court other famous European composers and violinists like Wenzel Pichl and Carl Ditters von Dittersdorf, who between 1765 and 1769 served as a Musikdirektor. Finally, in 1771, the Holy Roman Empress (jure uxori), Maria Theresa of Austria, together her son, future Joseph II, Holy Roman Emperor, arrived here to visit and make peace with a place whose project she did not initially fancy. In 1773 the palace unfortunately burned down entirely in a mysterious fire, but was reconstructed immediately by the next appointed bishop, after its original plans. In the year 1855, a new side and entrance was added graciously in tone and respect with the initial building, with grand double stairways.
