Trogir (Croatian pronunciation: [ˈtrɔ.ɡiːr]; Latin: Tragurium; Ancient Greek: Τραγύριον, Tragyrion or Τραγούριον, Tragourion[3]), historically known as Traù[4] (from Dalmatian, Venetian and Italian: pronounced [traˈu]) is a historic town and harbour on the Adriatic coast in Split-Dalmatia County, Croatia, with a population of 10,923 (2011)[5] and a total municipal population of 13,192 (2011).

In the 3rd century BC, Tragurion was founded as a colony by Ancient Greek colonists[8] on the Illyrian coast from the island of Vis, and it developed into a major port until the Roman period.

The diocese of Trogir was established in the 11th century (abolished in 1828; it is now part of the Roman Catholic Archdiocese of Split-Makarska and has temporarily been a Latin titular bishopric).

In the year 1000, the Republic of Venice received submission from the Tragurium inhabitants and the city started since then to have commerce with the Italian peninsula enjoying cultural and economic improvements.

In about 1650 a manuscript of the ancient Roman author Petronius' Satyricon was discovered at Trogir which contained the Cena Trimalchionis ("Trimalchio's Dinner").

Trogir has a high concentration of palaces, churches, and towers, as well as a fortress on a small island, and in 1997, was inscribed in the UNESCO World Heritage List.

"The orthogonal street plan of this island settlement dates back to the Hellenistic period and it was embellished by successive rulers with many fine public and domestic buildings and fortifications.

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.

The most important sites include: The St. Peter Church was part of the women's Benedictine monastery which was, according to the legend, founded by the wife of king Bela IV of Hungary.

The west front of the church is embellished by a Baroque portal decorated with a bust of St. Peter, the work of Niccolo di Giovanni Fiorentino.

The wooden ceiling dating from that period is divided into oval, semioval and hexagon fields, framed by richly decorated borders.

The front of this Renaissance building, which was executed by Niccolo di Giovanni Fiorentino, is decorated with the sculptures of St. Sebastian and Christ the Saviour.

In 1471, the workshop of Niccolo di Giovanni Fiorentino executed a relief of Justice on the eastern wall, depicting the Venetian lion with S. Lawrence and B. John of Trogir, both guardians of the city.

The Garagnin-Fanfogna Palace is constituted of two blocks of Romanesque and Gothic buildings, incorporated into the ensemble in the second half of the 18th century, after the plans of Ignacije Macanović.

The library owned by Ivan L. Garagnin (1722–1783), a numismatist and collector of archaeological monuments, is decorated with wall paintings portraying philosophers and writers.

There is a rich collection of early Dalmatian and Venetian sacred paintings (14th–15th century) with masterpieces of Gentile Bellini, Paolo Veneziano, Quirizio da Murano and others.

Works of local masters, paintings of Blaž Jurjev Trogiranin [Blase, son of George from Trogir] or the 13th century polyptych of the cathedral's high altar are exhibited in the Pinacotheca.

Tourism is the most important economic factor in the Trogir region, covering 50% of the municipal budget with more than 20,000 beds in hotels and private apartments.

It also doubled for 19th century Venice in the 2015 BBC miniseries Jonathan Strange & Mr Norrell,[14] and was used for scenes set in the city of Qarth in the HBO series Game of Thrones.
