The study can be discerned with two moments. The first part unfolds Vallgravsstråket’s obscure historical legibility by looking into the subject’s conditional processes of creating/producing heritage with focus on Vallgravsstråket’s local identity and place-based memory. The second part of the thesis focuses on the area’s opera- tive practicality by studying the consequences of constructing a footbridge over Vall- gravsstråket with the help of a morphological analysis. A recurring question involves understanding what makes up Vallgravsstråket and why it is important to preserve it and, for whom. Along these lines, it has been interesting to identi- fy an inconsistent gap between how the area is currently represented, what is commonly stated in legally binding documents and, how the local users evaluate the area. The aim of the study is to unveil different perspectives on Vallgravsstråket in order to obtain a better comprehension of the subject’s cultural-historical, legal and morphological dimen- sions. The thesis of this dissertation as such, has an inductive nature and grounds from a holistic approach that is motivated by a pluralistic view of reasoning where knowledge cannot be reasoned from one single particular perspective. The dissertation starts out with an intersubjective field study that introduces the area’s ‘urban walls’, ‘urban rooms’ and ‘urban experience’. The thesis then shifts its focus on Vallgravsstråket’s urban development by outlining the significant changes in the history of Gothenburg and analysing the impact of planning interventions. Vallgravsstråket’s urban elements, that is to say, parks, bridges and canal, are evaluated as thematic chapters. The dissertation then exemplifies a qualitative text analysis of legal documents that concern the named area with the purpose of understanding how or why certain approaches have surfaced in debates and researches. After having assessed an adequate empirical background on Vallgravsstråket, the last and final coordinated academic ef- fort has been to experiment with a morphological analytical method both in theory and practice.

INTRODUCTION When Gothenburg was founded in the early 1600s it was enclosed with a fortification wall that protected the town from neighbouring Scandinavian countries that for centuries fought over stabilising the nations’ borders and trading privileges. Two centuries later the town had outgrown its need of a protective barrier system and sought after opening up the town with green areas and freestanding civic institutions, which resulted with the construction of Vallgravsstråket. Geographically, Vallgravsstråket extends from Yttre Järnvågsbron in the west to Slussbron in the east and can be described as a green ring of parks, squares and canals around Gothenburg’s historic core. The area comprises a diverse mixed- use function that creates possibilities for cultural and social exchange, shopping, and recreational promenade. Vallgravsstråket is classified as an area of national interest and portrays a significant role in Gothenburg’s townscape from a cultural and historical perspective, as much as in a social and environmental perspective. At a closer glance, however, Vallgravsstråket’s representation as an area of national interest implicates mixed meanings in planning terms. I had never reflected on Vallgravsstråket’s symbolic features until I came to study the area in a previous urban analysis as- signment, which in turn, kindled an interest for exploring the subject further in a graduation thesis. Much of this thesis is dedicated in unveiling Vallgravsstråket’s underlying characteristics and discussing the implicit conflicts and potentials in conceptualizing the area’s place-based memory. 1 . 1 B A C K G R O U N D ropean Architectural Heritage Year” took the form of a campaign and spread over three years resulting with 1.1.1 HERITAGE PRESERVATION AND pilot projects in participating countries.
