What is it?

Just outside the seaside town of Piran are shallow ponds where workers have been making sea salt by hand for over 700 years. The sun and wind dry the seawater until only a layer of white salt is left.

Tell me more

Salt-makers ('solinari') wade through the ponds with wooden rakes, gathering the salt into small pyramids.

Piran's most famous salt is 'fleur de sel' - delicate flakes that form on the surface and are harvested before sunrise.

Each pond is lined with a special layer of grown-on algae called 'petola' - a Slovenian invention that keeps the salt clean.
