At first, Megalochori, which is a village 15 km north of modern Plomari, 600 m. high in the mountains, was called Plomari and it can be considered the metropolis of Plomari.
Fear of the pirate invasions kept the residents of Plomari far from the sea for a lot of years. But when conditions of security were established and there was no fear of pirates, Plomarians came to live near the sea and started building their new town in the place where it is today.
With the help of experienced sailors, some of whom came from the South Aegean Sea, Plomarians built up a good navy.
Besides that, they were occupied with agriculture and with their hard work and patience they changed the mountains to endless olive tree fields by building low stone walls even on the steepest mountainous slopes to create the suitable territorial conditions for the growing of olive trees.  

There are great beaches in Plomari as the seaside summer resort of Agios Isidoros and the western seaside neighborhood Ammoudeli are famous beyond locals and visitors.

Accessed by sea, ‘Panagia Krifti’ is a protected landscape of a picturesque little church in a cave near a hot spring secluded in a dramatic scenery of ancient olive trees, tall sharp-edged rocks, and deep unexplored caverns.
