Fadlum Spring Saltworks is one of the historical natural spring-salt production areas around central Sivas. The site is important not only for salt production but also for its surviving Ottoman-era operating structures, microorganisms adapted to high salinity and the traditional spring-salt culture of Sivas.
Geographical Location
Fadlum Saltworks lies around Tepeönü village in the central district of Sivas. Records in the Ministry of Culture and Tourism’s Culture Portal state that the operating structure is located at Kubu Başı locality in Tepeönü village.
The central Sivas region is characterised by high plateaus, a harsh continental climate and broad sedimentary basins. Evaporitic horizons within these basins allow naturally saline groundwater sources to form.
How Does Spring Salt Form?
The production system at Fadlum is based on saline groundwater. After rain and snowmelt infiltrate underground, water passes through salt-bearing geological layers and dissolves sodium chloride. This mineralised water reaches the surface through suitable fractures, cracks and permeable horizons.
When the saline water reaching the surface is evaporated in shallow ponds with the help of sun and wind, dissolved salt crystallises.
Fadlum in MTA Data
In MTA’s table of industrial raw materials in the Sivas region, Fadlum is recorded as the Sivas Central-Fadlum Saltworks. The same source reports a brine density of 23.5 Baumé and a flow rate of approximately 36 kg per minute.
The Baumé scale has historically been used to express the density of saline solutions. It is not directly equivalent to percentage salt content, but it helps indicate the high mineral concentration of the solution.
Ottoman-Era Operating Heritage
One of the most notable features of Fadlum is the survival of its historical operating building. The Culture Portal lists the structure in the cultural inventory of the Ottoman period.
The building contains sections with different functions, including management space, storage and a dining area. This architectural organisation indicates that salt production was not merely a seasonal outdoor activity; it required an institutional system of administration, storage and workforce organisation.
Transport and Public Investment
Historical records of the Grand National Assembly of Türkiye refer to road construction and stabilisation works on the road to the Sivas-Fadlum Saltworks. This shows that the saltworks was regarded as an economically significant production point in regional transport planning.
Academic Microbiology Research
Fadlum has been used as a sampling site in academic studies of microorganisms adapted to the high salinity of Sivas spring saltworks.
These environments act as natural laboratories for halophilic bacteria and archaea capable of living at high salt concentrations.
Spring Saltworks and Local Society
Production at historical spring saltworks involves more than harvesting salt crystals. Directing brine into ponds, preparing the ponds, monitoring crystallisation, collecting, drying, storing and transporting the product all create distinct labour processes.
In rural regions, these processes may be associated with seasonal employment, local knowledge and family labour.
Environmental Sensitivity
Water management is one of the central environmental issues at spring saltworks. Naturally saline water should not mix uncontrollably with freshwater systems, pond drainage needs to be managed, and the natural salinity regime of the production area should be protected.
The presence of halophilic microbial communities also shows that saltwork ponds are distinctive extreme ecosystems as well as production areas.
Fadlum in the Sivas Salt Atlas
Because of its historical Ottoman operating structure, MTA records, highly mineralised spring water and academic microbiology research, Fadlum is one of the best-documented spring saltworks in Sivas.

Where and How Should Rock Salt Be Purchased?
This page is a historical and geological inventory of a region, mine or natural salt source. No automatic origin relationship should be inferred between the site discussed here and any commercial product sold on the market. The actual origin of a product should be checked from the producer and origin declarations on its own packaging.
When purchasing salt for food use, the package should be checked for traceability information such as the name and address of the producer or food business operator, establishment registration number, batch or lot number, date information, net quantity and an accurate product description.
