The building is a historical monument, situated on Piaţa 1 Decembrie street, built in 1913 , representative of the Hebrew community of Oradea. Ullmann Izidor is one of the Jews established Ullmann. An entrepreneurial spirit like his father, Sándor built the Ullmann palace, with plans by the arhitecht Lőbll Ferenc.

The Viennese Secession style building has three floors built on a high floor and a loft. The ground floor is fully built , but the floors are developed around an inner courtyard . The facade is symmetrical and beautifully proportioned, the penultimate bay are slightly curved forming the bay windows at the first and second floors, with semicircular window-doors above the balconies, the facade ending with a trapezoidal attic. On the exterior decoration of the façade we can decipher specific elements of Jewish sacred art: Menorah (candlestick with seven branches) guarded by two lions and numerous floral and geometric elements . The ground floor was coated with blue-green tiles.

The building was conceived with an interior courtyard designed to be a tenement building (apartment building) for well off families. The apartments facing the street were designed very luxurious , while those facing the courtyard , more modest , they were for the servants. Originally in the building was an Old Rite Israelite Chapel.

During the Second World War the Ullmann Palace was part of the ghetto area , here and in the area the Jews were gathered and than they were deported to the extermination camps.
After the war, Ullmann Palace became once again what was before , an apartment building and in the attic was arranged a workshop for professional artists .
