Based in Hamburg, the Interessengemeinschaft Seezeichen e. V. (IGSZ) is an association bringing together enthusiasts of lighthouses and maritime navigation aids.
It unites historians, former maritime administration professionals, institutions, companies and collectors who are committed to the study and promotion of maritime heritage.

As part of this partnership, the IGSZ contributed to the translation of the museum texts at the Phare de Grave, helping to make the content accessible to an international audience.
This collaborative effort reflects a living partnership, rooted in the sharing of knowledge and a shared passion for the history and heritage of lighthouses.
