The article reviews Ernő Foerk’s career through the perspective of his sacred buildings. Ernő Foerk’s oeuvre accounts for a significant proportion of these works. Most of his accomplished churches were made in a Historicist style with a Latin-cross-shaped plan and facade tower. His designs which remained on paper, however, show a more diverse picture from both spatial and stylistic aspect. A number of plans were marked together with Gyula Petrovácz, however, we should presume Foerk had a more significant role in the artistic formation. In addition to the general historicist language, his works also had unique stylistic features, which were mainly related to the design of towers’ proportions, windows, pediments and spires, and to the use of bricks in facade design.
