This comprehensive historical
and engineering archive covers the
monumental 20th-century hydrological
infrastructure projects in Brussels.

Provenance & Rarity:
This entire collection originally
belonged to the Chief Engineer
of the project. It represents a
lifelong professional gathering
of data, reports, and imagery.

and exhaustive collection.

Absolute Authenticity:
This is a one-of-a-kind individual
