Situated below the mountain and Nature Park Ucka, Opatija (old name: Abbazia) is a great choice for a vacation in summer and winter season.It is a popular summer and winter resort, with average temperatures of 10°C in winter, and 25°C in summer. Opatija is surrounded by beautiful woods of bay laurel. The whole sea-coast to the north and south of Opatija is rocky and picturesque, and contains several smaller winter resorts.
The old 14th-century Benedictine abbey, Opatija Sv. Jakova ("Abbey of Saint Jacob"), from which the town derives its name (opatija means "abbey" in Croatian) is located in Park Svetog Jakova or Saint Jacobs Park. The Saint Jacob church, built in 1506 and enlarged in 1937, now stands on the same spot. The neo-Romanesque Church of the Annunciation with its pronounced green cupola, was designed in 1906 by architect Karl Seidl.
The city's most prestigious sight is the Villa Angiolina, which was built in 1844 by Iginio Scarpa, a rich merchant from Rijeka. This villa, transformed into a hotel, gave a boost to tourism to this town. It became a fashionable destination for the Austrian imperial family and Austrian nobility. Soon more luxury hotels and villas were built, such as the Hotel Kvarner, built in 1884. A new railway line was extended to Rijeka, from where one could go by tram to Opatija. The Austrian emperor Franz Joseph I used to spend here several months during winter. Many of these late 19th-century luxury hotels and villas have survived to present times.
