A damp morning on the River Can, and you’re following footprints that aren’t quite yours—echoes of engineers, couriers and experimenters who once threaded these streets. The quest opens with the former Marconi Hall Street Works: brick, soot-darkened, and humming in memory. As you move from the factory to the cathedral, the city’s surfaces feel alive—stone bridge arches creak with history and cobbles remember the clack of early motors.
