This publication makes the case for historic resources as investable assets for the comprehensive and sustainable revitalization of many at-risk and culturally significant communities throughout the world. It presents studies of six examples from across the world where heritage investment has transformed historic urban centers that had been in economic and cultural decline and were restored to places of vibrancy. A housing investment company in Amsterdam, a World Bank loan in Fez, a visionary private investor in Mexico City, entrepreneurial businesses in Panama City and Yangon, and a government-supported loan program in the UK succeeded in catalyzing more than a billion USD in leveraged capital.
