The first ever Summer Edition of the Jardins Abertos festival took place over two consecutive weekends in September, 4/5 and 11/12.
In addition to the usual virtual and physical format, the Summer Edition of the festival had both daytime and night-time programmes, allowing participants to see Lisbon’s gardens in a different light. Gardens like Procuradoria Geral da República, Estufa Fria, and Estrela Garden were open later than usual, the latter with a guided tour in the evening. In the warmth of the night, flowers that only open in darkness perfume the air and signal their presence to nocturnal pollinators.
The Summer Edition 2021 was attended by more than 33,000 participants — 10,557 in person and 22,254 virtually.
