Monnoyeur celebrates 120 years of building the future

Founded in 1906, Monnoyeur celebrates 120 years of entrepreneurship, innovation and commitment.
From a family business established in France to an international group operating in 24 countries, our journey has been shaped by generations of employees, the trust of our customers and partners, and a constant drive to create value.
Today, through our businesses and companies, we support customers across construction, energy, industry, agriculture and digital transformation.
120 years of innovation. 120 years of services. 120 years of solutions. And this is only the beginning.
120 years. A story in motion
Since 1906, Monnoyeur has grown through entrepreneurship, passion, expertise and, above all, the people who bring our Group to life every day.
From our historic roots to 24 countries today, generations of women and men have shaped our businesses, expanded our expertise and built lasting relationships across the world.
As we celebrate our 120th anniversary, we are not only looking back at our journey, but also looking ahead with the same spirit that has always driven us: to create, innovate, adapt and build the solutions of tomorrow.
Because our greatest legacy is the future we are building together.

A special anniversary celebration at our Saint-Denis headquarters
To mark Monnoyeur’s 120th anniversary, teams at our Saint-Denis headquarters came together for a special afternoon dedicated to our history, our people and our future. The programme included a special anniversary show hosted by our Executive Committee, featuring an inspiring film, speeches from Executive Committee members and presentations on key Group initiatives.
The afternoon also provided an opportunity to celebrate our long-standing partnership with Gustave Roussy, enjoy a birthday cake together, take part in a commemorative photo session and receive a special 120th anniversary gift.

120 years celebrated across the Group
The celebration extended beyond our Saint-Denis headquarters, with teams across all our divisions and countries coming together to mark this important milestone in their own way. From France to our international locations, these celebrations reflect the diversity of our businesses, the strength of our collective spirit and the people who make Monnoyeur what it is today. A look back at the celebrations across our Group.




10 years of commitment, 120 years of history, one shared future
For 10 years, Monnoyeur and its Business Units have supported Gustave Roussy in advancing the fight against cancer and improving patients’ lives.
To mark our 120th anniversary, Monnoyeur is making an additional donation to support Gustave Roussy’s cooling cap project. This next-generation system helps reduce chemotherapy-induced hair loss, helping patients preserve their confidence, identity and quality of life throughout treatment. The donation will also help more patients access innovative supportive care and provide medical teams with the tools and training needed to support them.
