# L'Association Diocésaine de Paris L'Association Diocésaine de Paris is an Endowment / Foundation based in Paris, France. ## Overview - **Organization type:** Endowment / Foundation - **Headquarters:** Paris, France - **Region:** Europe - **Address:** 10 rue du Cloître Notre-Dame, 75004 Paris, France - **Assets under management:** Undisclosed - **Website:** dioceseparis.fr - **LinkedIn:** https://fr.linkedin.com/company/association-dioc-saine-de-paris ## Regulatory record - **Reports private funds:** No ## About The Association Diocésaine de Paris (ADP) was established under French law as a cultural association to manage the temporal goods of the Catholic Church within the Diocese of Paris. Archbishop Laurent Ulrich leads the association alongside a professionalized finance team including Directrice Financière Christelle Le Floch and Économe Diocésain Jean Chausse. The entity covers the costs of worship, youth education, and solidarity efforts across the diocese, with resources drawn from real estate holdings, marketable securities, and donor contributions channeled through affiliated foundations. The ADP deploys capital primarily through a fund-of-funds program in French private equity, as indicated by its membership in France Invest and the institutional investor association Af2i. Its real property is concentrated in prime Paris arrondissements — 10 rue du Cloître Notre-Dame, 8 rue de la Ville-L'Évêque, 28 avenue George V, and a mansion on Rue Barbet-de-Jouy among them — alongside suburban land holdings in Aubervilliers. The residential portfolio counts approximately 291 units, while the commercial and mixed-use inventory supports parish offices and operational facilities. The securities portfolio and the specialized SICAV Porteurs d'Espérance round out a diversified treasury. The ADP's eight named professionals oversee a sprawling balance sheet whose scale remains undisclosed. Secretary General Ambroise Laurent coordinates economic and legal affairs, while Sylvie Bretones manages resource development and serves as Delegate General of Fondation Notre Dame, the primary fundraising arm supporting diocesan works. Affiliated foundations — Fondation des Bernardins, Fondation KTO, Fondation Avenir du Patrimoine à Paris, and Fondation pour l'Insertion par le logement — extend the institution's reach into cultural, media, and social housing initiatives, each maintaining separate governance but operational ties to the diocesan center. The treasury and marketable securities are managed internally, with private-equity exposure accessed through third-party managers within the France Invest network. The structural differentiator rests in the hybrid asset-owner model: a religious institution operating under a 1905 French law framework, holding both a working commercial real estate portfolio and a cultural treasury of incalculable heritage value, while simultaneously executing a modern private-equity fund-of-funds strategy. This dual character — custodian of the Relics of the Passion and an allocator to French mid-market buyout funds — creates a portfolio with no generic institutional parallel. ## Sectors - Real Estate - Private Equity - Infrastructure ## Offices - 4 rue de l'Asile Popincourt, 75011 Paris, France - 26 rue du Général Foy, 75008 Paris, France - 8 rue de la Ville-L'Évêque, 75008 Paris, France - 28 avenue George V, 75008 Paris, France - Rue Barbet-de-Jouy, 75007 Paris, France - Aubervilliers, France ## People - Mgr Laurent Ulrich — Archbishop of Paris and President - Jean Chausse — Économe Diocésain - Christelle Le Floch — Directrice Financière - Ambroise Laurent — Secretary General for Economic and Legal Affairs - Sylvie Bretones — Resource Development Director and Delegate General of Fondation Notre Dame - Robert Leblanc — Vice-President of Fondation Notre Dame - Jean-Baptiste de Franssu — President of the IOR and Chairman of the Board of the Collège des Bernardins ## Questions ### Who runs investment decisions at L'Association Diocésaine de Paris?
