The main concept with sustainable heritage is the idea that a heritage is sustained through economic, social, or environmental ways. A site that shows the concept of sustainable heritage is the Historic Bridgetown and its Garrison, Barbados. This world heritage site is an old British colonial architecture consisting of a well-preserved old town and a nearby military garrison on a small island developing state. It still has the 17-cetentury organic street layout resembling English market towns, which is not found at any other Caribbean territory.
The Barbados World Heritage Committee created ways to sustain this small islands heritage. They integrated World Heritage management principles in daily operations and implements programs such as the Physical Development Plan which help guide the effective sustainable management of the property which help raise awareness of its existence of the community.
Also, some areas on the island are very poor and undereducated which hinders on the potential heritage it has to offer. Sustainable development of the property in communities that have been overlooked helped these depressed World heritage communities. An area known as Nelson Street is highly overlooked at. It actually was an area where skilled artisan and tradespeople lived in the late 19th century and now in the 21st century, it has become associated with crime and poverty. The Pineland Creative Workshop is a nonprofit organization that has helped with the sustainability of this area by educating and facilitating economic and social opportunities for the community.
