The Corinth Canal is an artificial canal in Greece, that connects the Gulf of Corinth in the Ionian Sea with the Saronic Gulf in the Aegean Sea. It cuts through the narrow Isthmus of Corinth and separates the Peloponnese from the Greek mainland, arguably making the peninsula an island. The canal was dug through the Isthmus at sea level and has no locks. It is 6.4 kilometres (4 miles) in length and only 24.6 metres (80.7 feet) wide at sea level, making it impassable for many modern ships.

The archaeological site of Mycenae is securely located between two hills and the grassy plain of Argos stretches before this ancient city. Mycenae was the most important city in the Greek peninsula during the late years of the Bronze Age and gave its name to one of the most pioneering civilizations of this era: the Mycenaean civilization.

One of the most beautiful towns in the area of Argolis (in eastern Peloponnese) as well as one of the most romantic cities all over Greece, Nafplio was the first capital of the newly born Greek state between 1823 and 1834.

The fortress of Palamidi is a true architectural masterpiece. This fort was built during the Venetian occupation in the early 19th century and consists of eight bastions, each was self-contained, ensuring that if one bastion was breached the others could still be separately defended. The bastions were built one on top of the other and they all connected with one wall. The Venetians named the bastions by ancient Greek names, such as Leonidas, Miltiades, Achilles, Themistocles, to give emphasis on the strength of the castle.
