Large expanses of glass in the French style, and echoes of other times. Located on the right of the Prefect’s house, the bright nineteenth-century greenhouses retain all the charm of a story-book past. Works on the construction of these buildings for the acclimatization and protection of delicate plants began in 1808, during the period of French rule, and were completed in the Habsburg era. Three large halls are interconnected by smaller intermediate rooms. A thorough period-sensitive renovation undertaken in 2019 restored the structures to their original glory. Here visitors can admire the green magnificence of the Liberty-style glasshouse and the collection of carnivorous plants, of varying provenance but used to the same marshy, acidic and nitrogen-poor conditions: while able to perform photosynthesis, these plants procure the precious mineral they lack by “feeding” on insects and other small animals.
