Basilica of Sant'Eufemia, Grado

Grado (Venetian: Gravo; Friulian: Grau; Slovene: Gradež; Latin: Gradus) is a town and comune (municipality) of 8,064 residents in the Regional decentralization entity of Gorizia in the north-eastern Italian region of Friuli-Venezia Giulia, located on an island and adjacent peninsula of the Adriatic Sea between Venice and Trieste. The territory of the municipality of Grado extends between the mouth of the Isonzo and the Adriatic Sea and the Grado Lagoon, and covers an area of about 90 square kilometers between Porto Buso and Fossalon. Characteristic of the lagoon is the presence of the casoni, which are simple houses with thatched roof used in the past by the fishermen of Grado, who remained in the lagoon for a long time, returning to the island of Grado only during the colder period of the year. Once mainly a fishing centre, today it is a popular tourist destination, known commonly as L'Isola del Sole ("The Island of the Sun"). It is also famous because it is a spa town; from 1873 a maritime hospice for children called Ospizio Marino wanted by the doctor Giuseppe Barellai was established on the island, because the climate and the environment of the island are a good place for the treatment of some childhood diseases. Subsequently, Grado was the chosen destination for marine thermal treatments, especially by the Austrian population. Together with Marano Lagunare, it is the centre of the Marano-Grado Lagoon, which is famous for its uncontaminated nature. Grado is the birthplace of Biagio Marin, a poet who sang about the island in the local Venetian dialect.

Barbana is a small island located at the northern end of the Grado Lagoon, near Trieste in north-east Italy. It is the site of the Santuario di Barbana, an ancient Marian shrine, whose origins date back to 582 when Elia, the Patriarch of Aquileia, built a church near the hut of a hermit from Treviso named Barbanus. The island, which can be easily reached by ferry from nearby Grado, is populated by a small community of Franciscan friars.

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.

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 Valle Cavanata Nature Reserve (Italian: Riserva Naturale della Valle Cavanata) is a 327-hectare (810-acre) protected area situated in the easternmost part of the Grado Lagoon in Grado, Italy.

The National Archaeological Museum of Aquileia is a museum in Aquileia, Friuli-Venezia Giulia, Italy. It is one of the largest museums in Italy on Roman civilization. The museum is located at the Cassis Faraone villa and holds collections of statues, household and ornamental furnishings, gems, and coins. The museum was inaugurated in 1882, building on the private collection of Gian Domenico Bertoli which had been held at via Poppone since the 1700s. The first exhibition of the collection was in 1807 at the baptistery of the Basilica of Aquileia. In 1879 the Bertoli collection was acquired, and expanded the collection. Constructions took place at the gardens of Villa Cassis to accommodate the acquisitions.

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.
