Industrialisation, deindustrialisation and urban transformation are processes that fundamentally alter spatial, social and economic structures, particularly in metropolitan areas. The district of Beykoz, located in the north-east of Istanbul, and especially its urban coastline along the Bosphorus, offers a unique example of a settlement where these processes can be observed in succession. This study examines the spatial transformation of Beykoz-Paşabahçe, located in the urban coastal area of Beykoz district, within the multi-layered network of relationships between capital, state, industry, labour, and space throughout its historical process. Beykoz's ongoing spatial transformation process, which began as a fishing village, then transformed into an industrial basin with the establishment of large-scale factories through state-led industrialisation efforts, and later underwent changes through local and central government interventions and capital investments following the closure/relocation of large industrial facilities, is examined within a relational approach. Such an approach reframes Beykoz not as a passive site shaped solely by top-down processes, but as an active agent capable of intervening in and reshaping the very forces that constitute it.
