Ponza

Ponza is the largest island of the Italian Pontine Islands archipelago, located 33 km south of Cape Circeo in the Tyrrhenian Sea. It is also the name of the commune of the island, a part of the province of Latina in the Lazio region.

The island was inhabited from neolithic through Roman times. According to local legends, Ponza was named after Pontius Pilate, Roman governor of Judea who tried Jesus of Nazareth for sedition against Roman rule. Pontius Pilate's family owned a grotto on Ponza, which is still named after him. The Pontius Pilate legend of Ponza's name has recently come into dispute amongst historians, because the name "Pontia" appears in Strabo's Geography. This pre-dates the birth of Pilate. It is not known if this is the same name as Ponza or a similar name. Also, Pontia means "Land of Bridges" in Latin, a name which could have been applied for Ponza's many naturally occurring arches and bridge-like landforms. Another theory is that the name is of Greek origin, from Greek pontos, πόντος, sea .
