This project examines the Portuguese Synagogue in Amsterdam, Netherlands as a casestudy for the impact and development of successful urban planning, and how certain culturalminorities such as Sephardic Jews within the Iberian Peninsula and Latin America shaped thecity’s geography over time. This research project argues that the exchange between thearchitecture and materials in the colonies, as well as the Dutch Baroque style that will ultimatelyshape the Sephardic Jewish community’s central synagogue and Jewish Quarter into the idealurban city model, ushered the Netherlands into a Golden Age. This research project ispredominantly focused on social and architectural history, specifically within marginalizedgroups that are often brushed to the outskirts of historical records. The scope of this project falls between the Dutch Golden Age and the Colonial Period. This project uses historiography,geographical and architectural analysis, and a critique of urban development. This project intends to analyze urban planning and how design influences a city’s overall economic andsocial success on a transatlantic world stage, as well as to critique and decolonize former colonial spaces.
