Former UNESCO World Heritage Sites
World Heritage Sites may lose their designation when the UNESCO World Heritage Committee determines that the designated site is not properly managed or protected. First, however, the committee would place a site it is concerned about on its list of World Heritage in Danger of losing their designation and attempt to negotiate with the local authorities to remedy the situation. If remediation fails, the committee then revokes its designation.
A country may also request to reduce the boundaries of one of its existing sites, in effect partially or fully delisting such properties. Under the World Heritage guidelines, a country must report to the committee whenever one of its properties "inscribed on the World Heritage List has seriously deteriorated, or when the necessary corrective measures have not been taken."
In 2007, Oman's Arabian Oryx Sanctuary was the first site to be removed from UNESCO's World Heritage List. The sanctuary had become a World Heritage Site in 1994. Poaching and habitat degradation had nearly wiped out the Oryx population. The delisting was done in accordance with the wishes of the government that reduced the sanctuary by 90 percent after oil had been found at the site. Only four breeding pairs of oryx were counted at the time of the removal of the designation.
On June 25, 2009 the committee of UNESCO voted to remove the status of World Heritage Site of the Dresden Elbe Valley on the basis that the Waldschlösschen Bridge that was under construction since 2007 would bisect the valley. The 20km long site had been selected as a World Heritage Site in 2004. The delisting was preceded by a long and protracted struggle between local Dresden authorities in favour of the bridge and their opponents. A referendum had been conducted in 2005 about building the bridge without informing the voters that the UNESCO designation was at stake. In 2006 the site was placed on the endangered list until 2008, at which time a one-year extension was granted. When the construction of the bridge continued, a second extension was declined and at its 2009 meeting in Seville the committee voted 14 to 5 to delist the site. This represents only the second delisting of a World Heritage Site. While a majority of local residents polled indicated that Dresden's UNESCO title was unnecessary, the delisting removed funding to support the site and has been termed an "embarrassment". The Waldschlösschen Bridge was officially opened in 2013.
Partially delisted sites
UNESCO removed Bagrati Cathedral from its World Heritage Sites in 2017, considering its major reconstruction detrimental to its integrity and authenticity. Both it and Gelati Monastery were inscribed as a joint World Heritage Site in 1994, then added to the endangered list in 2010. The World Heritage Committee voted in 2017 to retain Gelati Monastery on the list but exclude Bagrati Cathedral.
