UNESCO World Heritage Centre experts regularly review the state of the UN cultural agency's 1,157 World Heritage sites, and at a meeting in Riyadh in September, a committee of 21 UNESCO member states will review more than 200 sites and decide which to add to the danger list.
Other sites recommended to be put on the danger list this year are the cities of Kyiv and Lviv in Ukraine. UNESCO said corrective measures proposed by the Italian state are "currently insufficient and not detailed enough." It added that Italy "has not been communicating in a sustained and substantive manner since its last Committee session in 2021, when UNESCO had already threatened to blacklist Venice.
