The Cathedral of Saint Domnius (Croatian: Katedrala Svetog Duje), known locally as the Sveti Dujam or colloquially Sveti Duje, is the Catholic cathedral in Split, Croatia. The cathedral is the seat of the Archdiocese of Split-Makarska, headed by Archbishop Marin Barišić. The Cathedral of St. Domnius is a complex of a church, formed from an Imperial Roman mausoleum, with a bell tower; strictly the church is dedicated to the Virgin Mary, and the bell tower to Saint Domnius. Together they form the Cathedral of St. Domnius. The Cathedral of Saint Domnius, consecrated at the turn of the 7th century AD, is regarded as the oldest Catholic cathedral in the world that remains in use in its original structure, without near-complete renovation at a later date (though the bell tower dates from the 12th century). The structure itself, built in AD 305 as the Mausoleum of Diocletian, is the second oldest structure used by any Christian Cathedral.

The Temple of Jupiter (Croatian: Jupiterov hram) is a temple in Split, Croatia dedicated to the Ancient Roman god Jupiter. It is located in the western part of Diocletian's Palace near the Peristyle, the central square of the imperial complex. It was built between 295 and 305, during the construction of the Palace, and was probably turned into a Baptistery of St. John the Baptist in the 6th century, at the same time when the crypt dedicated to St. Thomas was built. Before the entrance to the Temple is one of the twelve sphinxes brought from Egypt by Emperor Diocletian. Scottish architect Robert Adam considered this temple to be one of Europe's most beautiful monuments.

The modern diocese was erected in 1828, when the historical archdiocese of Salona was combined with the Diocese of Makarska. It was elevated as an archdiocese and metropolitan see in 1969, restoring the earlier status of the archdiocese of Split, as it is also known. The diocese was also known as Spalato-Macarsca.

The Golden Gate (Croatian: Zlatna vrata, Latin: Porta Aurea), or "the Northern Gate", is one of the four principal Roman gates into the stari grad (old town) of Split. Built as part of Diocletian's Palace, it served as the main gate through which the Emperor entered the complex and was elaborately decorated to mark its status. Over the course of the Middle Ages, the gate was sealed off and lost its columns and statuary. It was reopened and repaired in modern times and now serves as a tourist attraction.

Split (; Croatian pronunciation: [splît] ; historically known as Spalato (from Venetian: Spàlato, and Italian: pronounced [ˈspalato]); see other names) is the second-largest city of Croatia after the capital Zagreb, the largest city in Dalmatia and the largest city on the Croatian coast. It lies on the eastern shore of the Adriatic Sea and is spread over a central peninsula and its surroundings. An intraregional transport hub and popular tourist destination, the city is linked to the Adriatic islands and the Apennine Peninsula. The city was founded as the Greek colony of Aspálathos (Greek: Ἀσπάλαθος) in the 3rd or 2nd century BCE on the coast of the Illyrian Dalmatae, and in 305 CE, it became the site of the Palace of the Roman emperor Diocletian. It became a prominent settlement around 650 when it succeeded the ancient capital of the Roman province of Dalmatia, Salona. After the sack of Salona by the Avars and Slavs, the fortified Palace of Diocletian was settled by Roman refugees. Split became a Byzantine city. Later it drifted into the sphere of the Republic of Venice and the Kingdom of Croatia, with the Byzantines retaining nominal suzerainty. For much of the High and Late Middle Ages, Split enjoyed autonomy as a free city of the Dalmatian city-states, caught in the middle of a struggle between Venice and Croatia for control over the Dalmatian cities. Venice eventually prevailed and during the early modern period Split remained a Venetian city, a heavily fortified outpost surrounded by Ottoman territory. Its hinterland was won from the Ottomans in the Morean War of 1699, and in 1797, as Venice fell to Napoleon, the Treaty of Campo Formio rendered the city to the Habsburg monarchy. In 1805, the Peace of Pressburg added it to the Napoleonic Kingdom of Italy and in 1806 it was included in the French Empire, becoming part of the Illyrian Provinces in 1809. After being occupied in 1813, it was eventually granted to the Austrian Empire following the Congress of Vienna, where the city remained a part of the Austrian Kingdom of Dalmatia until the fall of Austria-Hungary in 1918 and the formation of Yugoslavia. In World War II, the city was annexed by Italy, then liberated by the Partisans after the Italian capitulation in 1943. It was then re-occupied by Germany, which granted it to its puppet Independent State of Croatia. The city was liberated again by the Partisans in 1944, and was included in the post-war Socialist Yugoslavia, as part of its republic of Croatia. In 1991, Croatia seceded from Yugoslavia amid the Croatian War of Independence.
