The Serra dei Giardini is a historic glasshouse in the Castello district’s public gardens, restored and run as a community hub combining a plant nursery, café and cultural venue. Built in 1894 for the Biennale, it now hosts workshops, exhibitions and events with a strong focus on nature, sustainability and community. Surrounded by greenery away from the tourist crush, it is a peaceful spot for a coffee and a green-minded project worth supporting.
