Overview

• León XIV formally opened the complex on September 5 at Castel Gandolfo, marking the encyclical’s 10th anniversary and publicly assuming a project backed by Pope Francis.
• The site spans 55 hectares between Castel Gandolfo and Albano Laziale, featuring more than 3,000 plant varieties, an olive grove with over 1,000 trees, and a 700‑year‑old oak.
• The complex is certified energy‑zero with photovoltaic systems, advanced insulation, and circular water management, and it includes classrooms, conference spaces, a dining point, an emporium, and a didactic greenhouse.
• Training already underway teaches biodynamic and regenerative agriculture to students, professionals, and vulnerable communities, with additional courses announced for migrants, refugees, trafficking survivors, and people with disabilities.
• The Holy See says it intends to allow only electric, zero‑impact vehicles in the area in the near future, and organizers expect roughly 250,000 visitors annually.
