This study aims to demonstrate how the diverse waterside spaces were coexisted in Phra Nakhon area as the walled district of Bangkok in early twentieth century by using century-old cadastral maps, land-ownership registers and our own architectural surveys of existing buildings. Focusing on the patterns of canals, roads, land parcels and buildings of the century-old cadastral maps, firstly, we classify waterside spaces to five types and explains spatial composition of each type. Secondly, we analyze and characterize the relationship between spatial compositions, their locations, and land uses of waterside space into five types. Our study is the first study that integrates the century-old cadastral maps and corresponding land-ownership registers of Bangkok.
