Kinderdijk, Netherlands, September 7, 2009--Winds of change blew through the historic mill complex at Kinderdijk this week. For the first time, energy-efficient LED bulbs powered the popular Dutch tourist attraction's annual illumination.

Part of a UN World Heritage site, the windmills help pump water in and out of low-lying areas called polders. Centuries before the mills were built around 1740, a cat was spotted balancing atop a baby in a cradle during a flood, hence the name Kinderdijk ("child's dike")—or so the story goes.
