The '''Corinth Canal''' ({{langx|el|Διώρυγα της Κορίνθου|translit=Dioryga tis Korinthou}}) is a [[canal]] in [[Greece]] that connects the [[Gulf of Corinth]] in the [[Ionian Sea]] with the [[Saronic Gulf]] in the [[Aegean Sea]]. Completed in 1893, it cuts through the narrow [[Isthmus of Corinth]] and "separates" the [[Peloponnese]] peninsula from the rest of the [[Greece|Greek]] mainland. The canal was dug through the Isthmus at [[sea level]] and has no [[Lock (water navigation)|locks]]. It is {{convert|6.4|km|mi|sigfig=1|abbr=off}} in length and at 24.6 metres (80.7 feet) wide at sea level is impassable for many modern ships. It is currently of little economic importance and is mainly a tourist attraction.

The Corinth canal concept originated with [[Periander]] of [[Ancient Corinth|Corinth]] in the 7th century BC. Daunted by its enormity, he chose to implement the ''[[Diolkos]]'', a land trackway for transporting ships, instead.<ref name="Raepsaet, G. & Tolley, M. (1993), 256" /><ref name="Werner, Walter, 1997, 114" /> Construction of a canal finally began under Roman Emperor [[Nero]] in 67 AD, using Jewish prisoners captured during the [[First Jewish–Roman War]]. However, the project ceased shortly after his death.<ref name="Nero" /><ref name="gerster" /> In subsequent centuries, the idea intrigued figures like [[Herodes Atticus]] in the second century and, following their conquest of the Peloponnese in 1687, the [[Republic of Venice|Venetians]]. Despite their interest, neither of them undertook the construction.<ref name=":1" /><ref name=":2" />

Construction finally recommenced in 1881 but was hampered by geological and financial problems that bankrupted the original builders. It was completed two years later, but, due to the canal's narrowness, navigational problems, and periodic closures to repair [[landslide]]s from its steep walls, it failed to attract the level of traffic expected by its operators.

===Ancient attempts===
Several rulers of antiquity dreamed of digging a [[Cutting (transportation)|cutting]] through the isthmus. The first to propose such an undertaking was the [[tyrant]] [[Periander]] in the 7th century BC. The project was abandoned and Periander instead constructed a simpler and less costly overland [[portage]] road, named the ''[[Diolkos]]'' or stone carriageway, along which ships could be towed from one side of the isthmus to the other.<ref name="Verdelis, Nikolaos (1957), 526">Verdelis, Nikolaos: "Le diolkos de L'Isthme", ''{{Ill|Bulletin de correspondance hellénique|fr}}'', Vol. 81 (1957), pp. 526–529 (526)</ref><ref name="Cook, R.

The [[Diadoch]] [[Demetrius I of Macedon|Demetrius Poliorcetes]] (336–283 BC) planned to construct a canal as a means to improve his communication lines, but dropped the plan after his surveyors, miscalculating the levels of the adjacent seas, feared heavy floods.<ref name="Werner, Walter, 1997, 114" /><ref name=gerster>Gerster, Béla, "L'Isthme de Corinthe: tentatives de percement dans l'antiquité", ''Bulletin de correspondance hellénique'' (1884), Vol. 8, No. 1, pp. 225–232 (in French)</ref>

The philosopher [[Apollonius of Tyana]] prophesied that anyone who proposed to dig a Corinthian canal would be met with illness. Three Roman rulers considered the idea but all suffered violent deaths; the historians [[Plutarch]] and [[Suetonius]] both wrote that the [[Roman dictator]] [[Julius Caesar]] considered digging a canal through the isthmus but was assassinated before he could begin the project.<ref>{{Cite web|title=Plutarch • Life of Caesar|url=https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Plutarch/Lives/Caesar*.html|access-date=2020-08-03|website=penelope.uchicago.edu}}</ref><ref>[[Suetonius]], "[https://www.perseus.tufts.edu/cgi-bin/ptext?lookup=Suet.+Jul.+44 Lives of the Caesars: Julius Caesar]", 44.3</ref> [[Caligula]], the third [[Roman Emperor]], commissioned a study in 40&nbsp;AD from Egyptian experts who claimed incorrectly that the Corinthian Gulf was higher than the [[Saronic Gulf]]. As a result, they concluded, if a canal were dug the island of [[Aegina]] would be inundated. Caligula's interest in the idea got no further as he too was assassinated before making any progress.<ref>{{cite book|title=Peloponnese & Athens|author1=Facaros, Dana|author2=Theodorou, Linda|pages=155–156|publisher=New Holland Publishers|year=2008|isbn=978-1-86011-396-3}}</ref>

[[Image:Remains of Nero's Isthmus Canal in 1881.jpg|thumb|upright=1.2|Remains of [[Nero]]'s canal project in 1881]]
The emperor [[Nero]] was the first to attempt to construct the canal, personally breaking the ground with a pickaxe and removing the first basket-load of soil in 67&nbsp;AD,<ref name="Nero">{{cite web|url=https://www.perseus.tufts.edu/cgi-bin/ptext?lookup=Suet.+Nero+19|title=C.

The Roman workforce, consisting of 6,000 [[First Jewish–Roman War|Judean prisoners of war]], started digging {{convert|40|to|50|m|ft|adj=mid|-wide}} trenches from both sides, while a third group at the ridge drilled deep shafts for probing the quality of the rock (which were reused in 1881 for the same purpose).<ref name="gerster" /> According to Suetonius, the canal was dug to a distance of four [[Stadion (unit of length)|stades]] – approximately {{convert|700|m|ft}} – or about a tenth of the total distance across the isthmus. A memorial of the attempt in the form of a relief of [[Hercules]] was left by Nero's workers and can still be seen in the canal cutting today.<ref>{{cite book|title=Pausanias' Greece: Ancient Artists and Roman Rulers|last=Arafat|first=K.

===Construction of the modern canal===
The idea of a canal was revived after Greece [[Greek War of Independence|gained formal independence]] from the [[Ottoman Empire]] in 1830. The Greek statesman [[Ioannis Kapodistrias]] asked a French engineer to assess the feasibility of the project but had to abandon it when its cost was assessed at 40&nbsp;million [[gold franc]]s—far too expensive for the newly independent country. Fresh impetus was given by the opening of the [[Suez Canal]] in 1869, and, the following year, the government of Prime Minister [[Thrasyvoulos Zaimis]] passed a law authorizing the construction of a Corinth canal. French entrepreneurs were put in charge but, following the bankruptcy of the French company that had attempted to dig the [[Panama Canal]], French banks refused to lend money, and the company went bankrupt as well. A fresh concession was granted to the ''Société Internationale du Canal Maritime de Corinthe'' in 1881, which was commissioned to construct the canal and operate it for the next 99 years. Construction was formally inaugurated on 23 April 1882 in the presence of King [[George&nbsp;I of Greece]].<ref name="Countdown">{{cite web|url=http://www.aedik.gr/frontend/articles.php?cid=44&scid=51|title=The Countdown|access-date=25 July 2011|archive-url=https://web.archive.org/web/20120328044804/http://www.aedik.gr/frontend/articles.php?cid=44&scid=51|archive-date=28 March 2012|url-status=dead}}</ref>

The company's initial capital was 30,000,000 francs (US$6.0&nbsp;million in the money of the day), but after eight years of work, it ran out of money, and a bid to issue 60,000 bonds of 500 francs each flopped when less than half of the bonds were sold. The company's head, [[István Türr]], went bankrupt, as did the company itself and a bank that had agreed to raise additional funds for the project.<ref name="Johnson">{{cite book|last=Johnson|first=Emory Richard|title=Principles of Ocean Transportation|url=https://archive.org/details/principlesofocea00johnuoft|pages=[https://archive.org/details/principlesofocea00johnuoft/page/99 99]–102|publisher=D. Appleton|location=New York|year=1920}}</ref> Construction resumed in 1890, when the project was transferred to a Greek company, and was completed on 25 July 1893 after eleven years' work.<ref name="Countdown" />

=== After completion ===
The canal experienced financial and operational difficulties after completion. The narrowness of the canal makes navigation difficult. Its high walls funnel wind along its length, and the different times of the tides in the two gulfs cause strong tidal currents in the channel. For these reasons, many ship operators were unwilling to use the canal, and traffic was far below predictions. Annual traffic of just under 4&nbsp;million net tons had been anticipated, but by 1906 traffic had reached only half a million net tons annually. By 1913, the total had risen to 1.5&nbsp;million net tons, but the disruption caused by [[World War I]] resulted in a major decline in traffic.<ref name="Johnson" />

[[File:Canal of korinth greece.jpg|thumb|upright=1.7|right|The Corinth Canal seen from the air, showing the steep limestone walls which proved vulnerable to landslides]]
Another persistent problem was the heavily [[Fault (geology)|fault]]ed nature of the [[sedimentary rock]], in an active [[seismic zone]], through which the canal is cut.<ref>"[http://www.aapg.org/athens/fieldtrip2.cfm Geology and Ancient Culture Along the Corinth Canal] {{webarchive|url=https://web.archive.org/web/20080117115438/http://www.aapg.org/athens/fieldtrip2.cfm |date=17 January 2008 }}"</ref> The canal's high [[limestone]] walls have been persistently unstable from the start. Although it was formally opened in July 1893 it was not opened to navigation until the following November, due to landslides. It was soon found that the wake from ships passing through the canal undermined the walls, causing further landslides. This required further expense in building retaining walls along the water's edge for more than half of the length of the canal, using 165,000 cubic metres of masonry.<ref>"Corinth Canal". ''Johnson's Universal Cyclopedia: A New Edition'', Vol. 7, p. 484. A.J. Johnson & Co., 1895</ref> Between 1893 and 1940, it was closed for a total of four years for maintenance to stabilise the walls. In 1923 alone, 41,000 cubic metres of material fell into the canal, which took two years to clear out.<ref>{{Cite web|url=http://www.corinthcanal.com/history3.html|archiveurl=https://web.archive.org/web/20071117071010/http://www.corinthcanal.com/history3.html|url-status=dead|title=''Corinth Canal History: 1923 A.C. — Nowadays''|archivedate=17 November 2007}}</ref>

Serious damage was caused to the canal during [[World War II]]. On 26 April 1941, during the [[Battle of Greece]] between defending Allied troops and the invading forces of [[Nazi Germany]], German parachutists and [[Military glider|glider]] troops attempted to capture the main bridge over the canal. The bridge was defended by British and [[Australian and New Zealand Army Corps#World War II|Anzac]] forces<ref name=":0">{{Cite web |title=CHAPTER 19 — The Corinth Canal {{!}} NZETC |url=https://nzetc.victoria.ac.nz/tm/scholarly/tei-WH2Gree-c19.html |access-date=2023-06-03 |website=nzetc.victoria.ac.nz}}</ref> and had been wired for demolition.

In October 1944, as German forces [[Army Group E#Service history|retreated from Greece]], the canal was put out of action by German "[[scorched earth]]" operations. German forces used explosives to trigger landslides to block the canal, destroyed the bridges and dumped locomotives, bridge wreckage and other infrastructure into the canal to hinder repairs. The [[United States Army Corps of Engineers]] began to clear the canal in November 1947 and reopened it for shallow-draft traffic by 7 July 1948, and for all traffic by that September.<ref>{{cite book|title=Bricks, Sand, and Marble: U.S. Army Corps of Engineers Construction in the Mediterranean and Middle East, 1947–1991 | url=https://history.army.mil/html/books/bricks_sand_and_marble/CMH_45-2-1.pdf#page=13 | archive-url=https://web.archive.org/web/20100608064234/http://www.history.army.mil/html/books/bricks_sand_and_marble/CMH_45-2-1.pdf#page=13 | url-status=dead | archive-date=8 June 2010 | author1=Robert P.

===Modern use===
Because the canal is difficult to navigate for large vessels, it is mostly used by smaller recreational boats. A notable exception occurred on 9 October 2019, when the cruise ship [[MS Braemar|MS ''Braemar'']] became the widest and longest ship to transit the canal.<ref>{{Cite web|url=https://www.cnn.com/travel/article/cruise-ship-squeeze-canal-intl-scli/index.html|title=Huge cruise ship squeezes through Greek canal to claim record|last=Woodyatt|first=Amy|date=12 October 2019|website=CNN Travel|language=en|access-date=12 October 2019}}</ref>

In October 2019, the {{convert|22.5|m|ft}} wide, {{convert|195|m|ft}} long 900-passenger [[Villa Vie Odyssey|''Braemar'']]  cruise ship successfully set a new record for longest ship to pass through the canal.{{cn|date=March 2025}}

Ships can pass through the canal only one [[convoy]] at a time on a one-way system. Larger ships have to be towed by [[tugboat|tug]]s.<ref name="Goette" /> The canal is currently used mainly by tourist ships; around 11,000 ships per year travel through the waterway.<ref>{{cite news|url=https://www.intltravelnews.com/2014/02/corinth-canal|title=The Corinth Canal|work=International Travel News|date=February 2014|last=Bowman|first=Carol L.|page=12}}</ref>
