<P> The Peloponnese is a peninsula that covers an area of some 21,549.6 square kilometres ( 8,320.3 sq mi ) and constitutes the southernmost part of mainland Greece . While technically it may be considered an island since the construction of the Corinth Canal in 1893 , like other peninsulas that have been separated from their mainland by man - made bodies of waters , it is rarely , if ever , referred to as an `` island '' . It has two land connections with the rest of Greece , a natural one at the Isthmus of Corinth , and an artificial one by the Rio -- Antirrio bridge ( completed 2004 ) . </P>
