During the 1950s and 1960s, Luxembourg underwent a major economic-political transformation that allowed the country to position itself as an internationally recognised financial hub and centre for European affairs. The degree of influence that this economic- political evolution of Luxembourg had on the architectural and urban development of Luxembourg City marks the focal point of this thesis. Two iconic projects realised during the 1960s serve as case studies: The Grande-Duchesse Charlotte Bridge that functioned as the cornerstone of the city's urban expansion, and the Alcide-de-Gasperi Tower, which represents Luxembourg's integration into European affairs. The architectural and urban transformation during the 60s in Luxembourg City, was mainly driven by the political integration into European affairs, aiming to fulfil the city’s role as European capital. Fuelled by the rivalry between the three European capitals Brussels, Luxembourg and Strasbourg, architecture served as a political national branding tool, resulting in international recognition and economic growth. With its participation in the European Union, Luxembourg needed to create a strong image and international recognition, supported by its architectural infrastructure. Today, the European project is still incessantly growing, and Luxembourg as one of its capital cities is required to grow synchronously and adapt it’s image to contemporary ideologies. At the core of Luxembourgish politics remains the ambition to modernise the city's infrastructure in order to perpetuate its strong position within the European Union.
