The Peloponnese is a large peninsula in Greece. It is the part of Greece which is south of the Isthmus of Corinth.
The Peloponnese has many mountains and a long jagged coastline. The highest part is Mount Taygetus in the south.
There are four south-pointing peninsulas within the Peloponnese. They are called Messenia, the Mani Peninsula, Epidaurus, and the Argolid.
