The impressive Church of the Annunciation dates back to 1906 and is neo-Romanesque with three halls and a large green dome. It was started by the Austrians according to the designs of architect Karl Seidl and then completed by the Italians. All in all, this exceptional church is well worth a visit or just watching from the outside, as its imposing dome can be seen from great distances in Opatija, adding an artistic touch to the city.
