The Tribunal of Waters is one of the oldest courts of justice in Europe - apparently it was already working as it does today around the year 1000. It meets every Thursday at noon to solve any conflicts between farmers, mainly regarding the distribution of water for the fields. There are no lawyers, and all the proceedings are oral and public. The sentence is immediate, and every farmer accepts it. It was chosen as Intangible Cultural Heritage by the UNESCO in 2009.
The sitting men in black are the judges, who are elected among the farmers; the standing men are the parts, while they were presenting their arguments.
