World Heritage Sites in Croatia. Red dots mark cultural and green dots mark natural sites.

Currently, there are ten sites inscribed on the list and 15 sites on the tentative list. The first three sites, Historical Complex of Split with the Palace of Diocletian, Dubrovnik, and Plitvice Lakes National Park, were inscribed to the list at the 3rd UNESCO session in 1979. Further sites were added in 1997, 2000, 2008, 2016, and 2017.^[2] In total, there are eight cultural and two natural sites, as determined by the organization's selection criteria. Three of the sites are shared with other countries.^[2]

During the Croatian War of Independence, following the breakup of Yugoslavia, military confrontations took place in Dubrovnik (Siege of Dubrovnik) and in the Plitvice Lakes area. Extensive artillery damage in Dubrovnik and landmines laid around Plitvice resulted in the two sites being listed as endangered in 1991. Following their restoration, Plitvice and Dubrovnik were removed from the list of endangered sites in 1997 and 1998, respectively.^[3][4] Although Croatia's World Heritage Sites generate large numbers of visitors, new threats are emerging due to the detrimental effects of uncontrolled mass tourism.^[5][6]

UNESCO lists sites under ten criteria; each entry must meet at least one of the criteria. Criteria i through vi are cultural, and vii through x are natural.^[7]

Site	Image	Location	Year listed	UNESCO data	Description
Plitvice Lakes National Park		Plitvička Jezera	1979	98; vii, viii, ix (natural)	Over time, water has flowed over the natural limestone and chalk, creating natural dams which in turn have created a series of connecting lakes, waterfalls, and caves. The nearby forests are home to bears, wolves, and many rare bird species.[8]
Historical Complex of Split with the Palace of Diocletian		Split	1979	97; ii, iii, iv (cultural)	The palace was built by the Roman emperor Diocletian at the turn of the fourth century AD, and later served as the basis of the city of Split. A cathedral was built in the Middle Ages inside the ancient mausoleum, along with churches, fortifications, Gothic and Renaissance palaces. The Baroque style makes up the rest of the area.[9]
Old City of Dubrovnik		Dubrovnik	1979	95; i, iii, iv (cultural)	Dubrovnik became a prosperous Maritime Republic during the Middle Ages, it became the only eastern Adriatic city-state to rival Venice. Supported by its wealth and skilled diplomacy, the city achieved a remarkable level of development, particularly during the 15th and 16th centuries.[10]
Episcopal Complex of the Euphrasian Basilica in the Historic Centre of Poreč		Poreč	1997	809; ii, iv (cultural)	The episcopal complex, with its striking mosaics dating back to the 6th century, is one of the best examples of early Byzantine art and architecture in the Mediterranean region and the world. It includes the basilica itself, a sacristy, a baptistery, and the bell tower of the nearby archbishop's palace.[11]
Historic city of Trogir		Trogir	1997	810; ii, iv (cultural)	Trogir's rich culture was created under the influence of old Greeks, Romans, and Venetians. It is the best-preserved Romanesque-Gothic complex not only in the Adriatic, but in all of Central Europe. Trogir's medieval core, surrounded by walls, comprises a preserved castle and tower and a series of dwellings and palaces from the Romanesque, Gothic, Renaissance, and Baroque periods.[12]
Šibenik Cathedral of St James		Šibenik	2000	963; i, ii, iv (cultural)	The cathedral is a triple-nave basilica with three apses and a dome (32 metres (105 ft) high inside) and is also one of the most important Renaissance architectural monuments in the eastern Adriatic.[13]
Stari Grad Plain		Hvar	2008	1240; ii, iii, v (cultural)	The Stari Grad Plain is an agricultural landscape that was set up by the ancient Greek colonists in the 4th century BC, and remains in use today. The plain is generally still in its original form. The ancient layout has been preserved by careful maintenance of the stone walls over 24 centuries.[14]
Stećci Medieval Tombstones Graveyards*		Dubravka, Cista Velika	2016	1504; iii, vi (cultural)	Stećci (sing. stećak) or the medieval tombstones are the monolith stone monuments found in the regions of the present Bosnia and Herzegovina, parts of Croatia, Serbia, and Montenegro. They first appeared in the 12th century and reached their peak in the 14th and 15th century. There are two sites inscribed in Croatia, in Dubravka and in Cista Velika.[15]
Venetian Works of defence between 15th and 17th centuries*		Zadar, Šibenik	2017	1533; iii, iv (cultural)	This property consists of six components of defence works in Italy, Croatia, and Montenegro, spanning more than 1,000 kilometres between the Lombard region of Italy and the eastern Adriatic Coast. The introduction of gunpowder led to significant shifts in military techniques and architecture. Croatian sites include the defensive system of Zadar and St. Nicholas Fortress in Šibenik.[16]
Primeval Beech Forests of the Carpathians and Other Regions of Europe*		Paklenica, Northern Velebit National Park	2017	1133; ix (natural)	This transboundary site (shared with Albania, Austria, Belgium, Bulgaria, Germany, Italy, Poland, Romania, Slovakia, Slovenia, Spain, and Ukraine) encompasses the isolated refuges from which the European beech has spread across the continent since the end of the last Ice Age. This successful expansion is related to the tree’s flexibility and tolerance of different climatic, geographical and physical conditions.[17]

In addition to the sites inscribed on the World Heritage list, member states can maintain a list of tentative sites that they may consider for nomination. Nominations for the World Heritage list are only accepted if the site was previously listed on the tentative list.^[18] As of 2021, Croatia recorded fifteen sites on its tentative list.^[19]
