Examples of effective conservation of places matter to the world. They range from the 1960s Nubian campaign to safeguard Ancient Egyptian monuments from the waters of the Aswan Dam to the removal in 2018 of the Belize Barrier Reef from the List of World Heritage in Danger. Conservation is the core purpose of the World Heritage Convention and it may also be its biggest challenge.

    The following example shows how successes at specific sites now serve as models for conservation and sustainable(可持续性) development. A year after Vienna was included on the World Heritage List in 2001, the World Heritage Committee (WHC) expressed concerns about the architectural solutions and height of four planned towers of the Wien-Mitte project. This development project, close to the Historic Centre of Vienna in the site's buffer zone, the one that lies between two or more other areas, affected the urban scale(规模) and visual effects in and around the property(地产). As a result of the Committee's concerns, Vienna changed its building codes and launched a new design competition for the Wien-Mitte project to work out architectural plans with reduced size in keeping with World Heritage protection.

    The successful practice inspired the government of the city to invite over 600 experts and professionals from 55 countries to an international conference on World Heritage and contemporary architecture, held in Vienna in May 2005. The global discussion that followed, detailing an approach to managing conservation and development, was recorded in the UNESCO Recommendation in 2011.

    The Recommendation put forwards an all-rounded and combined approach to balancing urban heritage conservation and economic development, arguing that active protection and management of urban heritage supports the goal of sustainable development.

    The Recommendation supports the harmonious combination of contemporary involvement into the historic urban framework while holding on to values linked to history, memory and the environment.

    Imagine walking through an ancient city, then climbing a gate tower to take in a wonderful view of the city and its more than 600-year-old walls. You can hear the city's heartbeat in the air. This is the Ancient City of Pingyao in Shanxi Province, a place that should definitely be on your travel route if you enjoy history or ancient architecture since its origins can be traced back to more than 2,700 years ago.

    Located in the center of Shanxi Province, Pingyao is the hometown of Jin merchants, a group of merchants who actively dominated(支配) a booming commodity market throughout China for more than 500 years, especially during the Ming and Qing dynasties. After the founding of the People's Republic of China in 1949, the city's agriculture and manufacturing industries developed rapidly. Following China's reform and opening-up in the 1980s, Pingyao struggled with the transition from a managed economy to the current market-oriented economy.     During this time, the city government sought out new ways to break through this economic bottleneck.

    Finally in the winter of 1997, opportunity came knocking. Through the efforts of the city government, Pingyao earned its place on the UNESCO World Heritage list, which caused the entire world to take notice of the city.

    Since the city's fame has risen, locals in Pingyao have deepened their understanding of the conservation efforts preserving the historical relics in their hometown. Meanwhile the city administration has continued to upgrade itself through a strategy that follows the pillars(核心) of "conservation, entrepreneurship, development and protection."

Currently, the city is focused on establishing a sustainable industry that will enable it to continue to grow while also protecting its relics and introducing them to the world.
