Angkor, Cambodia One of the most important archaeological sites in South-East Asia, Angkor Archaeological Park contains the magnificent remains of the different capitals of the Khmer Empire, from the 9th to the 15th century.

In 1993, UNESCO embarked upon an ambitious plan to safeguard and develop the historical site carried out by the Division of Cultural Heritage in close cooperation with the World Heritage Centre. Illicit excavation, pillaging of archaeological sites and landmines were the main problems. The World Heritage Committee, having noted that these threats to the site no longer existed and that the numerous conservation and restoration activities coordinated by UNESCO were successful, removed the site from the List of World Heritage in Danger in 2004.

 The Old City of Dubrovnik in Croatia The ‘pearl of the Adriatic’, dotted with beautiful Gothic, Renaissance and Baroque buildings had withstood the passage of centuries and survived several earthquakes. In November and December 1991, when seriously damaged by artillery fire, the city was immediately included on the List of World Heritage in Danger. With UNESCO providing technical advice and financial assistance, the Croatian Government restored the facades of the Franciscan and Dominican cloisters, repaired roofs and rebuilt palaces. As a result, in December 1998, it became possible to remove the city from the List of World Heritage in Danger.

 The Wieliczka Salt Mine, near Cracow in Poland This property was inscribed in 1978 as one of the first twelve World Heritage sites. This great mine has been actively worked since the 13th century. Its 300 kilometres of galleries contain famous works of art with altars and statues sculpted in salt, all of which were seriously threatened by humidity due to the introduction of artificial ventilation at the end of the 19th century. The site was placed on the List of World Heritage in Danger in 1989. During nine years of joint efforts by both Poland and the international community, an efficient dehumidifying system was installed, and the Committee, at its session in December 1998, had the satisfaction of removing the site from the List of World Heritage in Danger.

 The Ngorongoro Conservation Area in the United Republic of Tanzania This huge crater with the largest concentration of wild animals in the world was listed as an endangered site in 1984 because of the overall deterioration of the site due to the lack of management. By 1989, thanks to continuous monitoring and technical cooperation projects, the situation had improved and the site was removed from the List of World Heritage in Danger.
