St. Vitus’ Cathedral is the only Baroque rotunda of monumental proportions built on Croatian soil. The construction of this church, designed by the Jesuit architect G. Briano, began in 1638. It was made on the model of the famous Venetian church of Santa Maria della Salute. http://www.visitrijeka.eu/What_To_See/Monuments/St._Vitus_Cathedral

The Trsat Castle represents a strategically embossed lookout on a hill 138 meters above sea level dominating Rijeka. It was mentioned as a parochial centre for the first time in 1288. At this same site there was a Liburnian observation post from prehistoric times, used for monitoring the roads leading from the hinterland to the coast. http://www.visitrijeka.eu/What_To_See/Attractions/Trsat_Castle
