The Isthmus of Corinth (
Greek: Ισθμός της Κορίνθου) is the narrow land bridge which connects the

, to the east the
Saronic Gulf. Since 1893 the
Corinth Canal has run through the 6.3 km wide isthmus, effectively making the Peloponnese an island. Today, two road bridges, two railway bridges and two
submersible bridges at both ends of the canal connect the mainland side of the isthmus with the Peloponnese side. Also a military emergency bridge is located at the west end of the canal.
History of the canal
The idea for a shortcut to save boats sailing all round the Peloponnese was long considered by
the Ancient Greeks. The first attempt to build a canal there was carried out by the tyrant
Periander
Periander (; el, Περίανδρος; died c. 585 BC) was the Second Tyrant of the Cypselid dynasty that ruled over ancient Corinth. Periander's rule brought about a prosperous time in Corinth's history, as his administrative skill made Corinth o ...

Diolkos

road. Remnants of Diolkos still exist today next to the modern canal.
When the
Romans took control of Greece, a number of different solutions were tried.
Julius Caesar
Gaius Julius Caesar (; ; 12 July 100 BC – 15 March 44 BC), was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in a civil war, and ...
foresaw the advantages of a link for his newly built
Colonia Laus Iulia Corinthiensis. By the reign of
Tiberius, engineers tried to dig a
canal, but were defeated by lack of modern equipment. Instead they built an
Ancient Egyptian device: boats were rolled across the isthmus on logs, as the Egyptians had rolled blocks of
granite to make their
pyramids. This was in use by AD 32. In AD 67, the
philhellene Roman emperor
Nero ordered 6,000 slaves to dig a canal with
spades. Historian
Flavius Josephus writes that the 6,000 slaves were
Jewish pirates, taken captive by
Vespasian during the Jewish wars. According to
Pliny the Elder, the work advanced four
stadia (about 0.8 kilometers). The following year Nero died, and his successor
Galba
Galba (; born Servius Sulpicius Galba; 24 December 3 BC – 15 January AD 69) was the sixth Roman emperor, ruling from AD 68 to 69. After his adoption by his stepmother, and before becoming emperor, he was known as Livius Ocella Sulpicius Ga ...
abandoned the project as being too expensive.
In the modern era, the idea was first seriously proposed in 1830, soon after Greece's
independence from the
Ottoman Empire, and was brought to completion in 1893 after eleven years' work.
Preservation efforts
