Contemporary cities are facing the challenge of integrating public spaces, transport systems, and commercial functions, which is reflected in the revitalization processes of historic buildings. In the transformation of urban spaces, it is essential to preserve cultural heritage while respecting the historical value of architectural monuments and adapting them to contemporary needs and the principles of sustainable development. These include improving energy efficiency, employing renewable energy sources, and implementing circular economy practices. This article presents selected issues related to the comprehensive redevelopment and revitalization of the Warszawa Wileńska Railway Station—a historic facility originally constructed in 1862 as the Petersburg Station. The project, carried out under challenging conditions involving continuous passenger traffic, dense urban development, and proximity to historic tenement buildings, required the development of non-standard design, logistical, and fire safety procedures. Moreover, the construction process necessitated close cooperation with Polish State Railways (PKP) and numerous other institutions. This investment serves as an example of an innovative approach to the revitalization and integration of railway infrastructure with a multifunctional and commercially oriented shopping complex, becoming a symbol of modern revitalization efforts.
