Eje Ambiental

This guide to Eje Ambiental in Bogotá traces the buried San Francisco river beneath this pedestrian promenade, ordered underground by a 1915 city law after officials called the open water a public disgrace. A second law the following year billed the cost to property owners along the banks, and wealthy blocks near Carrera Cuarta and Plaza San Victorino paved over their stretch within a couple of decades. Look down at the dark, curving line cut into the brick to trace the river's old course as you walk.
