We strongly support the proposal of the UNESCO World Heritage Center to the World Heritage Committee at the 44th session (16-31 July 2021) under the chairmanship of the People’s Republic of China to place Venice and its Lagoon on the UNESCO List of World Heritage in Danger without further delay. This is the latest of our appeals to UNESCO, in collaboration with other representatives of civil society, that began in 2015 when the first delegation representing the UNESCO World Heritage Centre visited Venice. This was followed up with a detailed document containing contributions from all the main local organisations. We wrote again prior to the 2019 UNESCO World Heritage Committee meeting in Baku, Azerbaijan, and presented further information and continuing concerns during the delegation’s second official visit in January 2020. We are concerned about the credibility of UNESCO’s World Heritage List if the Committee does not officially designate Venice and its Lagoon as endangered World Heritage, and decisiveness at this critical moment would trigger the State Party (a total of 20 authorities both at the national and local levels in charge of the site’s protection and management) to engage in the vital discussions and timely actions that the Site so desperately needs. Here you can read the full letter to the UNESCO signed by WahV with FAI Venezia, Cittadini per l’aria, WWF Venezia e Territorio and LIPU Venezia.
