This thesis explores the Hanse’s legacy goes the exchange of goods, understanding how medieval trade networks also transported intangible practices, such as ideas, customs, and shared practices across Northern Europe. It discusses that such practices — from common legal frameworks and rituals for commerce to building techniques and a common language — were as important to the Hanse’s world as warehouses and ships. Such commonalties produced a cohesive identity across borders and diverse cities, leaving a mark on urban life and potentially a collective memory. By examining key trade outposts and the cultural ties that bound them, the research reveals a network held together not only by commerce but by a mutual understanding and governance that transcended borders. Further, the thesis assesses how this layered heritage is represented today, and how the existing taxonomy of the Water Museum Network could assist. It finds that the taxonomy could classify museums and archives which commemorate the Hanse’s history, they could further include heritage which represents this rich history.
