The former waterworks on the elb island "Kaltehofe" provided Hamburg with drinking water for over a hundred years. The waterworks was closed in 1990 and untouched for 20 years. And reopened in 2010 as museum that now shows informations about the history and the nature.
Hamburg: Second largest city of Germany, situated in the north at the river Elbe, because of the seaport well known as a city of merchants. Because of the nearby sea, you will always have some fresh breeze while you are walking through the streets with nice private town-houses or while you are floating along aboard an “Alsterdampfer” on the river Alster.
