Kostanjevica Franciscan Monastery with the Church of the Annunciation of Our Lady stands on a hill dividing the town of Nova Gorica and the suburb of Pristava. It is located just some 200 meters from the border with Italy. It is famous as the burial place of Charles X of France and his family.
In 1623 as small Carmelite sanctuary was erected just outside the limits of the town of Gorizia. In the next hundred years, a monastery was built next to the church, while the monastic chapel became an important site for pilgrims from Friuli and Goriška regions. In 1781, the monastery was disbanded by the Habsburg Emperor Joseph II. In 1811, the Franciscan friars acquired the abandoned complex, re-establishing the monastery. Among other, they brought a notable library containing some 10,000 books, which they transferred from the nearby Sveta Gora monastery. Today, the library is named after Father Stanislav Škrabec, a renowned Slovene linguist from the 19th century who lived and worked in the monastery for more than 40 years.
The Kostanjevica monastery was severely damaged in the Battles of the Isonzo during World War I. It was restored between 1924 and 1929. Until the end of World War II, the monastery was part of the town of Gorizia. In 1947, the border between Italy and Yugoslavia was set just a few hundred meters westward from the monastery, and Kostanjevica became part of the newly established town of Nova Gorica.
In the 19th century, the crypt of the Franciscan monastery was used for the burial of members of the French House of Bourbon who went into exile after the July Revolution. Most of them had settled in Gorizia, then part of the Austrian Empire, in the 1830s. The most famous of these is Charles X of France, King of France and Navarre.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
