Flywheel in pumping station Woudagemaal at work. Driven by steam. Lemmer, province Friesland, the Netherlands, January 2013.

‘The largest functioning steam pumping station in the world dates from 1920 and has been on the UNESCO World Heritage List since 1998. This monumental steam giant is still used by Wetterskip Fryslân when water levels are too high to ensure dry feet in Friesland’ (source: Woudagemaal)
