We would like to single out a few more cities and monuments which belong to the anthology of the European art heritage. The Roman Antiquity of the classical period has left a strong mark on the city of PULA, where today we can still admire the magnificent Amphitheatre with the best preserved architectonic shell in Europe, the Triumphal arch of the Sergeians and the Temple of Augustus from the 1st century. Nearby the late-antique Diocletian's palace in Split, lie the remnants of SALONA, capital of the Roman province of Dalmatia. In Salona, the early Christian age left an immense archaeological treasure, without which the history of European Christianity would be unimaginable. The Pre-Romanesque period marked Zadar with the rotunda of St. Donat, one of the largest central churches in the 9th century Europe, comparable with the Chapel of Carl the Great in Aachen from the same period. The Romanesque epoque made Krk, Rab and Trogir remarkable with numerous houses (seldom found in Europe) and great churches and convents. STON and MALI STON were built during the Gothic period, as two planned cities connected by walls with towers that spread several kilometers in length. It was one of the most extensive fortification undertakings during the 14th century and used by the Dubrovnik Republic to defend the whole of the Peljesac penninsula. Also during the Gothic period, this time in the North, in Zagreb, the easternmost Catholic Cathedral in the whole of Europe was built, as well as the fortress Medvedgrad, near Zagreb, with its octagonal chapel. The Renaissance shaped the character of the coastal towns OSOR, PAG, SIBENIK, HVAR and DUBROVNIK, whereas the Baroque left its strongest mark in the northern cities of VARAZDIN, BJELOVAR, POZEGA, SLAVONSKI BROD, VUKOVAR, and many others. The 19th century saw the development of RIJEKA and OSIJEK into larger cities, with beautiful examples of Art Nouveau architecture, and especially of ZAGREB, which is also significant for its numerous buildings of the "Zagreb School" of modern architecture between the two World wars, which united both the functionalism by Le Corbusier and the organic architectural approach by Frank Lloyd Wright.
