Dubrovnik is a city on the Adriatic Sea in the region of Dalmatia, in southern Croatia. It is one of the most prominent tourist destinations in the Mediterranean Sea, a seaport and the centre of Dubrovnik-Neretva County. In 1979, the city of Dubrovnik was added to the UNESCO list of World Heritage Sites in recognition of its outstanding medieval architecture and fortified old town. A feature of Dubrovnik is its walls, which run almost 2 kilometres (1.2 miles) around the city. The walls are 4 to 6 metres (13–20 feet) thick on the landward side but are much thinner on the seaward side. The system of turrets and towers were intended to protect the vulnerable city. The walls of Dubrovnik have also been a popular filming location for the fictional city of King's Landing in the HBO television series, Game of Thrones.
Zagreb is the capital and largest city of Croatia. It is in the northwest of the country, along the Sava river, at the southern slopes of the Medvednica mountain. The etymology of the name Zagreb is unclear. It was used for the united city only from 1852, but it had been in use as the name of the Zagreb Diocese since the 12th century and was increasingly used for the city in the 17th century. Zagreb is an important tourist center, not only in terms of passengers traveling from the rest of Europe to the Adriatic Sea, but also as a travel destination itself. Since the end of the war, it has attracted close to a million visitors annually, mainly from Austria, Germany, and Italy, and in recent years many tourists from far east (South Korea, Japan, China, and last two years, from India). It has become an important tourist destination, not only in Croatia, but considering the whole region of southeastern Europe.
Plitvice Lakes is the oldest and largest national park in the Republic of Croatia. The park is situated in the mountainous region of Croatia, between the Mala Kapela mountain range in the west and northwest, and the Lička Plješivica mountain range to the southern. With its exceptional natural beauty, this area has always attracted nature lovers, and already on 8 April 1949, it was proclaimed Croatia’s first national park. The process of tufa formation, which results in the building of the tufa, or travertine, barriers and resulted in the creation of the lakes, is the outstanding universal value, for which the Plitvice Lakes were internationally recognised on 26 October 1979 with their inscription onto the UNESCO World Heritage List. In 1997, the boundaries of the national park were expanded, and today it covers an area just under 300 km2. The park is primarily covered in forest vegetation, with smaller areas under grasslands. The most attractive part of the park – the lakes – cover just under 1% of the total park area.
The most valuable cultural property in Poreč, the Euphrasian Basilica, was registered on the list of UNESCO World Heritage Sites in 1997. The early-Christian compound is the only complete landmark in the world preserved from that period. Built during the time of Bishop Euphrasius in the 6th century it includes atrium, baptistery, bishop's palace, mosaics and remains of sacral buildings dating from the 3rd to the 4th centuries. The mosaics which decorate the inside and facade of the church are considered a valuable bequest of Byzantine art, and thanks to the floor mosaics and preserved writings the periods of its construction and renovation can be read.
Diocletian Palace is one of the best preserved monuments of the Roman architecture in the world. The Emperor's Palace was built as a combination of a luxury villa - summer house and a Roman military camp (castrum), divided into four parts with two main streets. Southern part of the Palace was, in this scheme, intended for the Emperor's apartment and appropriate governmental and religious ceremonies, while the north part was for the Imperial guard - the military, servants, storage etc. The Palace is a rectangular building with four large towers at the corners, doors on each of the four sides and four small towers on the walls. Over the centuries the Palace inhabitants, and later also the citizens of Split adapted parts of the palace for their own requirements, thus the inside buildings as well as the exterior walls with the towers significantly changed the original appearance, but the outlines of the Imperial Palace are still very visible.
