For most of the twentieth century, architecture has learned to read cities through roads. Street hierarchies define urban plans, intersections organize movement, and buildings are understood by the façades they present to sidewalks. Roads appear so fundamental to urban life that they are often mistaken for a universal condition. Across much of Southeast Asia, cities developed according to an entirely different spatial logic. Long before automobiles reordered urban landscapes, rivers served as streets, marketplaces, civic spaces, and public infrastructure. Movement occurred primarily by boat, commerce unfolded along waterfronts, and architecture addressed water rather than asphalt. Reading these cities through their waterways changes how architecture itself is understood. Infrastructure, in this case, is not the road but the river.
