Wagner's first realized major project was an Orthodox Synagogue on Rumbach Street in Budapest. His design was selected in a competition held in 1868, when he was twenty-seven years old. The octagonal hall of the synagogue was concealed behind a four-story structure facing the street. The hall was filled with light from stained glass windows on the octagonal lantern above, and large circular windows in each of the eight bays. On the first floor above the ground floor was an octagonal gallery reserved for women. The facade was made of brick of different colors, and was decorated with minarets and towers with a Moorish appearance, while the interior featured colorful patterns of mosaic slender on the walls and highly decorated columns which supported arches over each of the bays.
