The Water Museum and the History of Sanitation, Buenos Aires, Argentina

This is also known as El Palacio de las Aguas Corrients, or the Palace of Running Water, and it is spectacularly beautiful inside and out. In the mid-19th century, Buenos Aires was experiencing massive population growth and several epidemics, including cholera and yellow fever. So the city decided to fix the water supply. It took 7 years to build, finiahws in 1894, and it contains 12 water tanks (provided by a Belgian firm) with a total capacity of 72 million liters of water. The style of this building is quite eclectic and is yet another example of the upper classes of Argentina fancying everything European. Almost everything was pre-fabricated in Europe. There are over 300,000 tiles making up the exterior of the building, each individually numbered to enable easy placement. In addition to being a water and plumbing museum, it is also where you go to pay your water bill.
