London grew by absorbing many older settlements along the Thames. The result is a large polycentric city with a winding river, irregular street fabrics and rail corridors that converge on terminals around the center.
Three traces to read
The Thames bends through the center
The river makes broad turns from west to east, narrowing through central London before widening toward the estuary.
Many centers, few perfect grids
Historic roads and former town centers create an irregular, layered pattern rather than a single planned downtown grid.
Radial rail and orbital movement
Mainline railways approach from every direction while underground lines and ring roads connect the dispersed centers.
What usually gives London away?
Start with the Thames' distinctive bends, then look for a vast, irregular street field crossed by many radial railways. The combination is more reliable than the river shape alone.
