The Corinth Canal (Greek: Διώρυγα της Κορίνθου, Dhioryga tis Korinthou) is a canal that connects the Gulf of Corinth with the Saronic Gulf in the Aegean Sea. It cuts through the narrow Isthmus of Corinth and separates the Peloponnese from the Greek mainland, thus effectively making the former peninsula an island. The builders dug the canal through the Isthmus at sea level; no locks are employed. It is 6.4 kilometres (4.0 mi) in length and only 21.4 metres (70 ft) wide at its base, making it impassable for most modern ships. It now has little economic importance.

The canal was mooted in classical times and an abortive effort was made to build it in the 1st century AD. Construction finally got underway in 1881 but was hampered by geological and financial problems that bankrupted the original builders. It was completed in 1893, but due to the canal's narrowness, navigational problems and periodic closures to repair landslides from its steep walls, it failed to attract the level of traffic anticipated by its operators. It is now used mainly for tourist traffic.

The canal consists of a single channel 8 metres (26 ft) deep, excavated at sea level (thus requiring no locks), measuring 6,346 metres (20,820 ft) long by 24.6 metres (81 ft) wide at the top and 21.3 metres (70 ft) wide at the bottom. The rock walls, which rise 90 metres (300 ft) above sea level, are at a near-vertical 80° angle. The canal is crossed by a railway line, a road and a motorway at a height of about 45 metres (148 ft). In 1988 submersible bridges were installed at sea level at each end of the canal, by the eastern harbour of Isthmia and the western harbour of Poseidonia.

Although the canal saves the 700-kilometre (430 mi) journey around the Peloponnese, it is too narrow for modern ocean freighters, as it can only accommodate ships of a width of up to 16.5 metres (54 ft) and a draft of 7.3 metres (24 ft). Ships can only pass through the canal one at a time on a one-way system. Larger ships have to be towed by tugs. The canal is nowadays mostly used by tourist ships; 11,000 ships per year travel through the waterway.

TheRio–Antirrio bridge (Greek: Γέφυρα Ρίου-Αντιρρίου), officially the Charilaos Trikoupis Bridge after the statesman who first envisaged it, is one of the world's longest multi-span cable-stayed bridges and the longest of the fully suspended type. It crosses the Gulf of Corinth near Patras, linking the town of Rio on the Peloponnese peninsula to Antirrio on mainland Greece by road.

The 2,880 m (9,449 ft) long bridge (approximately 1.8 miles) dramatically improves access to and from the Peloponnese, which could previously be reached only by ferry or via theisthmus of Corinth in the east. Its width is 28 m (92 ft) — it has two vehicle lanes per direction, an emergency lane and a pedestrian walkway. Its five-span four-pylon cable-stayed portion of length 2,252 m (7,388 ft) is the world's second longest cable-stayed deck; only the deck of the Millau Viaduct in southern France is longer at 2,460 m (8,071 ft). However, as the latter is also supported by bearings at the pylons apart from cable stays, the Rio–Antirrio bridge deck might be considered the longest cable-stayed "suspended" deck.

This bridge is widely considered to be an engineering masterpiece, owing to several solutions applied to span the difficult site. These difficulties include deep water, insecure materials for foundations, seismic activity, the probability of tsunamis, and the expansion of the Gulf of Corinth due to plate tectonics.

The Nafpaktos is a seaside town (altitude. 15m.) the Corinthian Gulf and belongs to the prefecture Aetoloakarnanias. Built between Antirrio and the mouth of Mornou river it is one of the oldest Greek cities that experienced periods of great prosperity and was associated with significant historical events. This is confirmed by the excellent fortification, which starts from the port, continues with three walls and ends at the castle. It has been declared a traditional settlement .
