Po River in the context of "Duke of Montferrat"

Venice is a city in northeastern Italy and the capital of the region of Veneto. It is built on a group of 118 islands that are separated by expanses of open water and by canals; portions of the city are linked by 438 bridges.

The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po and the Piave rivers (more exactly between the Brenta and the Sile). As of 2025, the city proper (comune of Venice) has 249,466 inhabitants, nearly 50,000 of whom live in the historical island city of Venice (centro storico), while most of the population resides on the mainland (terraferma), and about 25,000 live on other islands in the lagoon (estuario).

Montferrat (UK: /ˌmɒntfəˈræt/ MONT-fə-RAT, US: /-ˈrɑːt/ -⁠RAHT; Italian: Monferrato [moɱferˈraːto]; Piedmontese: Monfrà, locally [mʊŋˈfrɒ]; Latin: Mons Ferratus) is a historical region of Piedmont, in northern Italy. It comprises roughly (and its extent has varied over time) the modern provinces of Alessandria and Asti. Montferrat is one of the most important wine districts of Italy. It also has a strong literary tradition, including the 18th-century Asti-born poet and dramatist Vittorio Alfieri and the Alessandrian Umberto Eco.

The territory is cut in two by the river Tanaro. The northern part (the Basso Monferrato, "Low Montferrat"), which lies between that river and the Po, is an area of rolling hills and plains. The southern part (the Alto Monferrato, "High Montferrat") rises from the banks of the Tanaro into the mountains of the Apennines and the water divide between Piedmont and Liguria.

Casale Monferrato (Italian pronunciation: [kaˈzaːle moɱferˈraːto]) is a town in the Piedmont region of northwestern Italy, in the province of Alessandria. It is situated about 60 km (37 mi) east of Turin on the right bank of the Po, where the river runs at the foot of the Montferrat hills. Beyond the river lies the vast plain of the Po valley.

An ancient Roman municipium, the town has been the most important trade and manufacturing centre of the area for centuries. After the fall of the Roman Empire, Casale became a free municipality and, in the 15th and early 16th centuries, served as the capital of the House of Palaiologos. Then in 1536, the town passed to the Gonzagas who fortified it with a large citadel. In the 17th century, Casale was heavily involved in the War of the Mantuan Succession and besieged by French and Spanish troops. During the wars of Italian unification the town was a defensive bulwark against the Austrian Empire.

The Venetian Plain, or Venetian-Friulian Plain (Italian: Pianura Veneta or Pianura Veneto-friulana) is a major geographical feature of Italy. It extends approximately from the River Adige to the River Isonzo, in a southwest-to-northeast direction, including almost all the flatlands of Veneto and Friuli. The plain is divided into high and low plains with the high plain located between Brenta and Piave rivers. It is not properly related to the Po River basin, but it is often considered as part of the Po Valley since the flatlands of Veneto and Friuli do not drain into the Po, but they effectively combine into an unbroken plain. Sometimes, instead of the River Adige, the Euganei Hills and Berici Hills are considered to be its western border.

Tartaro-Canalbianco-Po di Levante (Latin: Tartarus) is a river of north-east Italy. It is the only river whose course runs between the Adige river and the Po river and flows into the Adriatic Sea.

The first part of its course, whose length is 52 kilometres (32 mi) from resurgences to Torretta, flows in the province of Verona and in the province of Mantua and is known by the name of Tartaro.The second part of its course, whose length is 78 kilometres (48 mi) from Torretta to Volta Grimana, flows in the province of Rovigo and is known by the name of Canalbianco or Canal Bianco (meaning White Canal in both Italian and Venetian).The third and final part of its course, whose length is 17 kilometres (11 mi) from Volta Grimana to mouth, flows in the province of Rovigo and is known by the name of Po di Levante (meaning Eastern Po).

Adria is a town and comune in the province of Rovigo in the Veneto region of northern Italy, situated between the mouths of the rivers Adige and Po. The remains of the Etruscan city of Atria or Hatria are to be found below the modern city, three to four metres below the current level. Adria and Spina were the Etruscan ports and depots for Felsina (now Bologna). Adria may have given its name during an early period to the Adriatic Sea, to which it was connected by channels.

Goro (Ferrarese: Gòr, but locally Goro) is a comune (municipality) in the Province of Ferrara in the Italian region Emilia-Romagna, located about 80 kilometres (50 mi) northeast of Bologna and about 50 kilometres (31 mi) east of Ferrara, near the mouth of the Po River.

Goro borders the following municipalities: Ariano nel Polesine, Codigoro, Mesola.

Polesine (Italian: [poˈleːzine]; unified Venetian script: Połéxine [poˈɰezine]; Ferrarese: Pulésan) is a geographic and historic area in the north-east of Italy whose limits varied through centuries; it had also been known as Polesine of Rovigo for some time.

Nowadays it corresponds with the province of Rovigo in the viewpoint of political geography. In the viewpoint of physical geography it is a strip of land about 100-km long and 18-km wide located between the lower courses of the Adige and the Po rivers, limited to the east by the Adriatic Sea and leaving the western limit undefined.
