10 Endangered UNESCO World Heritage Sites

Primarily due to human impact on the environment, these UNESCO heritage sites are quickly disappearing.

UNESCO World Heritage Sites are important cultural and natural places that preserve the history or nature of a place or country. UNESCO recognizes the way in which people and nature interact and the importance of preserving the balance between the two. While the United Nation compiles a list of heritage sites, it also has another list of sites that are considered to be in danger of losing their heritage status. The list of endangered world heritage site creates awareness on the threat to the features for which a property was listed as a heritage site and to challenge the governments to take action to rescue and protect the sites.

10. Coro and its Port - Venezuela

A historic home in Coro, Venezuela.

Coro is the oldest city in Venezuela and one of its earliest colonial towns, established in 1527. It is located on the coast of Falcon State, a few miles from its ports in the Caribbean Sea. Coro and its port have a wide cultural tradition that originates from the urban settlement founded by the Spanish who colonized the interior of the continent. The buildings of Coro and its Port La Vela are earthen and display the unique examples of traditional mud building techniques. It was designated a heritage site in 1993.

However, it was listed as an endangered site in 2005 due to the climate change, particularly the heavy rains which have caused significant damages to the city. The earthen technique used in building the Coro and its port is highly vulnerable to heavy rains as the earth has a low resistance to moisture.
