National Archaeological Museum of Aquileia

The Patriarchate of Aquileia was an episcopal see and ecclesiastical province in northeastern Italy, originally centered in the ancient city of Aquileia, situated near the northern coast of the Adriatic Sea. It emerged in the 4th century as a metropolitan province, with jurisdiction over the Italian region of Venetia et Histria. In the second half of the 6th century, metropolitan bishops of Aquileia started to use the patriarchal title. Their residence was moved to Grado in 568, after the Lombard conquest of Aquileia. In 606, an internal schism occurred, and since that time there were two rival lines of Aquileian patriarchs: one in New Aquileia (Grado) with jurisdiction over the Byzantine-controlled coastal regions, and the other in Old Aquileia (later moved to Cormons). The first line (Grado) continued until 1451, while the second line (Cormons, later Cividale, and then Udine) continued until 1751. Patriarchs of the second line were also feudal lords of the Patriarchal State of Aquileia. A number of Aquileian church councils were held during the late antiquity and throughout the middle ages. Today, it is an titular archiepiscopal see.

The Siege of Aquileia is a siege battle that took place in 238 in the town of Aquileia during the Year of the Six Emperors which resulted in the assassination of Maximinus Thrax.

Aquileia is an ancient Roman city in Italy, at the head of the Adriatic at the edge of the lagoons, about 10 kilometres (6 mi) from the sea, on the river Natiso (modern Natisone), the course of which has changed somewhat since Roman times. Today, the city is small (about 3,500 inhabitants), but it was large and prominent in classical antiquity as one of the world's largest cities with a population of 100,000 in the 2nd century CE and is one of the main archaeological sites of northern Italy. In late antiquity the city was the first city in the Italian Peninsula to be sacked by Attila the Hun. It is currently a comune (municipality) in the Regional decentralization entity of Udine, Friuli-Venezia Giulia.

The Battle of the Isonzo, the Battle of the Aesontius, or the Battle of the Isontius, is the name given to the battle fought on August 28, 489 on the banks of the Isontius River, not far away from Aquileia.

On 28 August, the two armies met on the banks of the Isontius. Theodoric defeated Odoacer, who retreated. A second battle was fought at Verona.

The Torre (Friulian: Tôr; Slovene: Ter) is a river of the Province of Udine in Friuli-Venezia Giulia, northeast Italy. It is the main right tributary of the Isonzo; the Torre together with its own tributary the Natisone drain a large part of the Isonzo basin. The river rises in the Julian Prealps at around 1,000 metres (3,300 ft) above sea level. It flows through the communes of Tarcento and Reana del Rojale, where, as a result of the karst topography, it disappears underground. From close to the eastern periphery of the city of Udine it follows a discontinuous course until joined by the Natisone near Trivignano Udinese. From here it flows briefly in the Province of Gorizia, receiving the torrent Judrio from the left, before returning to the Province of Udine and flowing into the Isonzo.

The island, which can be easily reached by ferry from nearby Grado, is populated by a small community of Franciscan friars.
