Sečovlje Salt Pans

Structure and use

Materials

• Seawater — Moved through evaporation ponds into crystallisation ponds, by gravity or pumps as site conditions and infrastructure allow.
• Petola (petula) — Maintained as a several-millimetre bed layer of algae, sadra and minerals in crystallisation beds; the park says it separates forming salt from mud.

1. The first written record in 804 concerns several small Piran salt pans, some owned by monasteries; it is not proof that the present Sečovlje pond layout existed then. City statutes from 1274–1278 explicitly list the Sečovlje pans alongside those at Fazan and Strunjan. This distinction matters: the documentary history is centuries old, while the age of any particular bank, sluice or pond is not established by that record.
2. The installation sits at the Dragonja estuary on Slovenia’s northern Adriatic coast. Its working landscape is divided into evaporation and crystallisation ponds. Seawater progresses from the evaporating ponds into crystallisers either by gravity or with pumps. The park describes wind-driven pumps at Fontanigge and motor pumping introduced at Lera under Austrian administration; the arrangement therefore varied by sector and period.
3. In the crystallisation beds, salt workers cultivate petola, also called petula in the park’s English text. It is a thin natural layer made of algae, sadra and minerals. The park explains its practical role: it keeps the forming salt from direct contact with mud. The European Commission’s Piranska sol PDO account also describes petola as an algae-and-mineral base and traces its use to 1358. The sources do not provide a construction specification for the beds or a detailed maintenance schedule.
4. The park reports that crystallisation ponds make up about one fifth of the existing ponds and that salt forms there after seawater has passed through the evaporation stage. Workers harvest salt daily using gaveri, wooden rakes used to draw it into piles. Dried salt is stored in designated warehouses. This is a salt landscape with working divisions and tools, not a single pan or a portable piece of equipment.
5. The history of production changed by sector. In 1903, the Austrian government reorganised Lera’s crystallisation basins and introduced motor-assisted conveyance; the history page says the schedule of gathering salt every seven to eight days was later abandoned in favour of daily collection. Production ceased permanently at Fontanigge and Fazan in 1968, while traditional production is preserved at Sečovlje today. The image reference shows modern evaporation ponds at Lera, not an historical reconstruction or a view of salt being harvested.
6. The site is also protected heritage and habitat. Sečovlje and Strunjan were proclaimed salina parks in 1990, and Sečovlje was listed as a wetland of international importance under the Ramsar Convention in 1992. The park states that today the cultural and environmental protection role takes precedence over the saltworks’ former regional economic role. This description does not give engineering dimensions, bank materials, or permission to enter or modify the working pans.
