At the opening, all stations were decorated with Zsolnay ceramics, and had entrances in an Art Nouveau style (except at the Opera House, so as not to disturb its view). The biggest station (the one at Deák Square) and the less decorated stations were designed by György Brüggermann, while the ones at Gizella Square and Oktogon were made by Albert Schickedanz and Fülöp Ferenc Herzog. The old ceramics from the stations are exhibited in the Underground Railway Museum, while some of them are still in place at Vörösmarty Street Station.
