Staff of the Suchard factory, rue Mercœur, in 1904.
A former Suchard factory in the heart of the 11th
At 10 rue Mercœur, the chocolate workshops have given way to 7,894 m² of offices. The building keeps its industrial character: original cast-iron columns, generous volumes and light from both sides.
Already in operation in 1904, the Suchard factory made chocolate on rue Mercœur until around 1986. The site kept a strong identity after production stopped. Between 2015 and 2020 it was fully restored to house offices, from the ground floor to the 7th floor. The renovation covered the infrastructure, energy performance and safety, while keeping the original features. In 2026, all the lifts are being replaced.
A street born at the foot of a convent
Long before the offices, rue Mercœur ran along the walls of a convent. It went on to see three centuries of workshops and factories.
The oldest section appears on Jouvin de Rochefort's map, along the grounds of the Hospitalières de la Roquette.
The road is still just an unpaved extension of rue de la Roquette.
It is laid out on the grounds of a former convent founded by the Duchess of Mercœur.
It is thought to be named after Philippe-Emmanuel de Lorraine (1558–1602), Duke of Mercœur and Governor of Brittany.
A neighbourhood of workshops and factories
For centuries, this was the furniture makers' district. Its courtyards and passages, such as the cour Viguès, still bear witness to it.
Textiles, metalworking, glass, ceramics and musical instruments: the 11th filled up with factories and workshops.
The former Suchard factory at 10 rue Mercœur is part of this history. Restructured between 2015 and 2020, it now houses offices.
