Founded in 1856, Fer à Cheval is the oldest continuously operating savonnerie in Marseille and one of the most important custodians of traditional Savon de Marseille production today.
The company remains one of the few makers still producing authentic Marseille soap using the historic cauldron process for which the city became famous. More than a soap manufacturer, Fer à Cheval has become a reference point for the preservation of Marseille's soap-making heritage and a leading voice in defining what genuine Savon de Marseille should be.
Awarded the French state's prestigious EPV (Entreprise du Patrimoine Vivant – Living Heritage Company) designation, Fer à Cheval is recognised for maintaining exceptional industrial and artisanal expertise. The savonnerie is also a founding member of the Union des Professionnels du Savon de Marseille, the organisation established to protect and promote authentic Marseille soap.
Why Fer à Cheval Matters
Many soap factories have operated in Marseille over the centuries. Few remain.
Fer à Cheval survived the industrialisation of soap production, changing consumer habits and the decline of traditional manufacturing that affected much of the industry during the twentieth century.
Today, the savonnerie occupies a unique position. It is both a working manufacturer producing soap at scale and a guardian of one of France's most recognised household products.
For many consumers, Fer à Cheval represents the benchmark against which other Marseille soaps are judged.
Visiting Fer à Cheval reveals something often absent from modern manufacturing: continuity. The buildings, workshops and cauldrons remain part of a working soap factory rather than a recreated heritage attraction.
Throughout the site, traces of generations of soap-making remain visible in the timber structures, brickwork and production rooms. The savonnerie is not preserved behind glass; it continues to produce soap every day.
A Working Savonnerie
Unlike many heritage brands that now outsource production, Fer à Cheval continues to manufacture soap in Marseille.
Its famous olive Savon de Marseille is produced using the traditional hot saponification method in large cauldrons, a process that takes several days and remains largely unchanged from historic Marseille practice.
The company also produces soap for a number of other brands. When you see the words Fabriqué à Fer à Cheval stamped into a cube of Marseille soap, it indicates that the soap was produced within the Fer à Cheval savonnerie, although formulations may vary according to the requirements of the brand being supplied.
The Cauldrons
The large cauldrons are the defining feature of traditional Marseille soap production. Oils, water, alkali and salt are slowly transformed over a process that takes several days, before the soap is washed, purified and prepared for cutting.
Fer à Cheval remains one of the few savonneries where this historic method continues to form the foundation of production. Several of the original cauldrons remain in use today, linking modern manufacture directly to Marseille's soap-making heritage.
Understanding the Fer à Cheval Range
While best known for traditional Savon de Marseille, Fer à Cheval has gradually expanded its range to include household cleaning products, liquid soaps, black soaps and fragranced body care.
What distinguishes the range is that it remains rooted in soap-making expertise. The company has not moved into beauty trends or lifestyle products. Instead, it continues to build on the practical qualities for which Marseille soap has been valued for generations: effective cleansing, ingredient simplicity and versatility throughout the home.
A Living Industrial Heritage
One of the most striking features of the savonnerie is the fabric of the building itself. Decades of soap production have left their mark on beams, roof structures and workshops, creating a working environment that reflects generations of continuous manufacture.
Unlike many historic brands, Fer à Cheval's heritage is not reconstructed. It remains embedded within the factory where production continues today.
At the far end of the cauldron room stands a shrine dedicated to the Virgin Mary, overlooking the workshops where Marseille soap has been produced for generations. She is regarded as a protector of the savonnerie, its soap makers and the soap itself, and remains an important presence within the factory today. Positioned above the historic cauldrons, the shrine reflects the continuity of a business where traditions are not preserved behind glass, but remain part of everyday working life.
Fer a Cheval and Savon de Marseille
For many people, Fer à Cheval is synonymous with Savon de Marseille itself.
The savonnerie remains one of the strongest advocates for traditional production methods and ingredient transparency, helping to preserve a soap-making tradition that has been part of Marseille's identity for centuries.
In a market where the term "Marseille Soap" is often used loosely, Fer à Cheval remains one of the clearest links between the historic product and its place of origin.
From Cauldron to Finished Soap
While the core soap-making method remains traditional, moulding, cutting and finishing operations have evolved over time. The result is a range that combines historic production methods with modern manufacturing standards.
Throughout the factory, the horseshoe emblem appears as a reminder of the savonnerie's origins. Adopted when Fer à Cheval was founded in 1856, it was intended to bring prosperity and success to the new business. Over time, it became one of the most recognisable symbols in Marseille soap making. Today, the horseshoe continues to be stamped into Fer à Cheval soap, linking each bar to more than 170 years of continuous production in the city where the company began.
