Origins and rise of the fortune
Ennobled in 1688 by Charles II, the Christyn de Ribaucourt lineage took root in Brabant through the legal and military roles of François Christyn and the strategic acquisition of land around Brussels. In the 19th century, Count Prosper brought Perk Castle into the family heritage, inaugurating a land capital transmitted intact to the current count, Daniel.

Ennobled as far back as 1688, the de Ribaucourts today convert their noble rank into a family fortune of 129 million euros thanks to a dual foundation: Sibelco shares inherited from the Emsens–de Sadeleer lineage and emblematic real estate assets such as Perk Castle, host of the eco-electro festival Paradise City.
Genesis of the fortune: alliances and value creation
- 1688 – 1850: land capital
Christyn de Ribaucourt lineage → acquisition of Perk Castle (1833) by Count Prosper; basis of the real estate heritage providing land rents. - 1900 – 1980: industrial diversification
Marriage of Christian de Ribaucourt with Florence de Sadeleer (Emsens granddaughter) → injection of Sibelco shares, a minerals multinational founded by the Emsens empire. - 1980 – 2025: estate structuring
Creation of civil companies followed by BV GUICHAPHI to hold unlisted shares, pool Sibelco dividends and fund domain conservation.

The current pillars of capital
Sibelco stake (≈ €75–85M)
| Element | 2024 data |
|---|---|
| Sibelco dividend | €55M paid to the family pool (Emsens + minority shareholders) |
| Ribaucourt estimated share | 3–4% → €1.8–2.2M/year |
| Valuation | Method: 12× multiple on dividend flows → €21–26M |
Why this is key? The absence of a listing protects against volatility while guaranteeing recurring returns, a pillar of passive wealth.
