Restoring the Historic Greenhouses at Bologna’s Botanical Garden
The University of Bologna’s Orto Botanico ed Erbario is undertaking a major external restoration of its two primary greenhouses. Founded in 1568 by Ulisse Aldrovandi, the historic site requires infrastructure upgrades to protect thousands of fragile plant specimens as environmental conditions shift.
In Plain English: The Clinical Takeaway
- Infrastructure Preservation: The project targets the deteriorating exterior surfaces of the botanical garden’s two main greenhouses, which house diverse tropical and arid plant species.
- Ecosystem Health: Upgrades are designed to maintain stable internal microclimates essential for preserving living biological collections used in ongoing botanical and pharmacological research.
- Public Health and Green Spaces: According to reports from unimpatto.unibo.it, the initiative forms part of a broader urban green-blue infrastructure strategy connecting the botanical garden with the Filippo Re Campus.
Climate Challenges and Plant Preservation in Bologna
Established in the heart of Bologna over four centuries ago, the Orto Botanico stands as one of the oldest academic botanical gardens in Europe. Its two primary greenhouses maintain distinct regional ecosystems that require precise environmental controls. The tropical greenhouse replicates the high humidity and thermal conditions of equatorial rainforests, housing orchids, bromeliads, coffee plants, and vital medicinal species. Meanwhile, the succulent greenhouse holds approximately 3,000 specimens adapted to arid environments, representing a collection initiated by botanist Giuseppe Lodi.
Weather extremes and continuous atmospheric exposure have steadily degraded the structural envelopes of these climate-controlled enclosures. Maintaining these living archives is critical for scientific study, as botanical collections provide foundational material for pharmacognosy and environmental science. As regional temperatures fluctuate due to broader climatic pressures, structural remediation ensures that researchers can continue studying plant adaptations and biochemical pathways without environmental compromise.
Campus Integration and Regional Funding Structure
According to supplementary project data detailed by unibo.it, the greenhouse restoration constitutes part of a larger, multi-phase urban renewal initiative. The broader project encompasses the Orto Botanico (Phase II) and the green spaces of the University’s Filippo Re Campus, covering a total area of 73,340 square meters.
| Project Financial Metric | Allocation / Value |
|---|---|
| Total Project Cost | €1,891,362.90 |
| Regional Funding Contribution | €1,494,177.00 |
| University of Bologna Funding | €397,185.90 |
| Target Area Coverage | 73,340 square meters |
Led by Project Manager Architect Massimo Mattioli, the development integrates scientific zones with public pathways through targeted environmental measures. These include expanding the arboreal canopy, permeable paving removal (desealing) to manage stormwater runoff, establishing two new bicycle stations linked to public transit, and installing rainwater storage systems for sustainable irrigation.
Future Trajectory of the University Botanical Infrastructure
Financial backing for the initiative is provided through European funds managed by the Emilia-Romagna region via the PR-FESR 2021-2027 program, specifically targeting urban and peri-urban green and blue infrastructure. With Phase I of the botanical garden upgrades already underway, completion of the current structural stralcio (stage) will secure the long-term operational integrity of the historic greenhouses. The integrated campus design ensures that scientific research, public education, and urban biodiversity preservation continue in tandem.
