By integrating historical heritage into socio-economic development, UNESCO has designated Luxembourg City as an awardee.

The Ministry of Culture, the City of Luxembourg, and the Luxembourg Commission for Cooperation with UNESCO jointly produced a short film, which was presented to the United Nations organization as part of the "World Heritage Cities" initiative. The film, titled "Luxembourg: vieux quartiers et fortifications" which translates to "Luxembourg: old quarters and fortifications," is around five minutes long and showcases the socio-economic development of the city, all while respecting the national cultural heritage.

According to the press release from the Ministry of Culture sent to RTL, UNESCO has designated Luxembourg City as one of the 20 most significant historical cities worldwide. The unique approach to managing historical heritage, along with cultural, intangible and natural resources, were some of the factors contributing to this decision. Other factors considered included "legislative framework, resources, community inclusion, and management system/plan."

Additionally, UNESCO awarded Luxembourg because of its modern legislative framework which has laws that actively support the protection of the environment and culture: Cultural Heritage Act of February 25, 2022 and the Nature and Natural Resources Protection Act of July 18, 2018.

Access to numerous resources and expertise, as well as the existence of a sustainable development plan, were also key criteria that led to the decision because of the efforts to promote world heritage awareness with inclusivity and digitalization. The Luxembourg City Tourist Office's plans for tourists met all the points required by the international committee.
