Gulf of Patras in the context of "Mollusc"

Patras (/pəˈtræs, ˈpætrəs/; Greek: Πάτρα, romanized: Pátra pronounced [ˈpatra] ; Katharevousa and Ancient Greek: Πάτραι; Latin: Patrae) is Greece's third-largest city and the regional capital and largest city of Western Greece, in the northern Peloponnese, 215 km (134 mi) west of Athens. The city is built at the foot of Mount Panachaikon, overlooking the Gulf of Patras.

As of the 2021 census, the municipality of Patras has a population of 215,922, while the urban population is 173,600. The core settlement has a history spanning four millennia. In the Roman period, it had become a cosmopolitan centre of the eastern Mediterranean whilst, according to the Christian tradition, it was also the place of Saint Andrew's martyrdom.

The Gulf of Corinth or the Corinthian Gulf (Greek: Κορινθιακός Κόλπος, romanized: Korinthiakós Kólpos, Greek pronunciation: [koɾinθiaˈkos ˈkolpos]) is an inlet of the Ionian Sea, separating the Peloponnese from western mainland Greece. It is bounded in the east by the Isthmus of Corinth which includes the shipping-designed Corinth Canal and in the west by the Rion Strait which widens into the shorter Gulf of Patras (part of the Ionian Sea) and whose narrowest point has been crossed since 2004 by the Rio–Antirrio bridge. The gulf is bordered by the large administrative divisions (regional units): Aetolia-Acarnania and Phocis in the north, Boeotia in the northeast, Attica in the east, Corinthia in the southeast and south and Achaea in the southwest. The tectonic movement across the gulf is comparable to parts of Iceland and Turkey, growing by 10 mm (0.39 in) per year.

In the Middle Ages, the gulf was known as the Gulf of Lepanto (the Italian form of Naupactus).

Antirrio (Greek: Αντίρριο, pronounced [aˈndirio], Latin: Antirrhium) is a town and a former municipality in Aetolia-Acarnania, West Greece, Greece. Since the 2011 local government reform it is part of the municipality Nafpaktia, of which it is a municipal unit. The municipal unit has an area of 50.794 km.

It is situated on the north side of the narrow (2.4 km) Strait of Rio, which separates the Gulf of Patras in the west from the Gulf of Corinth in the east. Since August 2004 the Rio–Antirrio bridge connects northwestern Greece with the Peloponnese. The name Antirrio means "opposite Rio".

The Rio–Antirrio Bridge (Greek: Γέφυρα Ρίου–Αντιρρίου), officially the Charilaos Trikoupis Bridge, is one of the world's longest multi-span cable-stayed bridges and longest of the fully suspended type. It crosses the Rion Strait between the Gulf of Corinth and Gulf of Patras, linking the town of Rio on the Peloponnese peninsula to Antirrio on mainland Greece by road. It opened one day before the Athens 2004 Summer Olympics, on 12 August 2004, and was used to transport the Olympic flame.

Cape Araxos (Greek: Ακρωτήριον Άραξος), also known as Cape Pappas (Άκρα Πάππα), is a cape in the northwest of the Peloponnese in Greece. It is the northwesternmost point of Peloponnese and separates the Gulf of Patras from the Ionian Sea. It lies at a distance of 30 km (19 mi) west of the city of Patras and very close to the village of Akrotirio Araxou. In 1877 a stone lighthouse was built, but it was destroyed during the Second World War and a modern lighthouse was installed after some years. The waters in the area are dangerous because of the continuous additions of sediments, eroding from the uplands of Aetolia-Acarnania via the rivers Acheloos and Evinos, The waters are quite shallow in some parts.

The Battle of Lepanto was a naval engagement that took place on 7 October 1571 when a fleet of the Holy League, a coalition of Catholic states arranged by Pope Pius V and led by the navies of the Republic of Venice and the Spanish Empire, inflicted a major defeat on the fleet of the Ottoman Empire in the Gulf of Patras. The Ottoman forces were sailing westward from their naval station in Lepanto (the Venetian name of ancient Naupactus – Greek Ναύπακτος, Turkish İnebahtı) when they met the fleet of the Holy League which was sailing east from Messina, Sicily.

Lepanto marks the last major engagement in the Western world to be fought almost entirely between rowing vessels, namely the galleys and galleasses, which were the direct descendants of ancient trireme warships. The battle was in essence an "infantry battle on floating platforms". It was the largest naval battle in Western history since classical antiquity, involving more than 450 warships. Over the following decades, the increasing importance of the galleon and the line of battle tactic would displace the galley as the major warship of its era, marking the beginning of the "Age of Sail".

The Rion Strait (Greek: Στενό Ρίου) is a strait that connects the Gulf of Corinth with the Gulf of Patras (and hence the Ionian Sea). The strait is spanned by the Rio–Antirrio Bridge which connects the town of Rio on the south with the town of Antirrio on the north. The strait is also known as the Strait of Lepanto or the Rio–Antirio Strait.
