Which canal in Greece cuts through the Isthmus of Corinth?

The canal in Greece that cuts through the Isthmus of Corinth is the Corinth Canal.

It connects the Gulf of Corinth in the Ionian Sea with the Saronic Gulf in the Aegean Sea. By slicing through the narrow land bridge, the canal separates the Peloponnese from mainland Greece and saves vessels from sailing around the much longer southern coast of the peninsula.

The idea is ancient. The Greek ruler Periander attempted a canal in the 7th century BC, but engineers instead built the Diolkos, an overland route for moving ships or cargo across the isthmus. A modern canal was finally completed on 25 July 1893.

The Corinth Canal is about 6.4 kilometres long and was dug at sea level, so it has no locks. Its steep rock walls and narrow width make it unsuitable for many modern commercial ships, but it remains valuable for smaller vessels and tourism. It is sometimes confused with the Panama or Suez canals, both of which serve much larger international shipping routes.
