Aula Leopoldina is one of the most beautiful Baroque ceremonial halls in Europe, located in the university's 18th-century main building on the Odra River bank. Built between 1728 and 1732, it features stunning illusionistic ceiling frescoes, gilded sculptures, and statues representing the sciences and arts. It still serves as the university's main ceremonial hall. The complex also includes the Oratorium Marianum with equally magnificent Baroque design and the Mathematical Tower offering rooftop panoramic views of the city. Audio guide is available in 7 languages. The halls may occasionally close for university ceremonies — check ahead to avoid disappointment
