Manneken-Pis was at first a fountain that played an essential role in the former distribution of drinking water since the 15th century. The system was well-known in all of Europe. Towards the end of the 17th century, the statue became more and more important in the city life. It was also a survivor of the bombardment of Brussels in 1695. Manneken-Pis became a precious good and enjoys a ceaselessly growing glory. During big events, we adorn him with luxurious clothes. We know that in the 18th century, Manneken-Pis was dressed at least 4 times a year. Since he lost his main function in the network of water conveyance of the City in the 19th century, Manneken-Pis gradually became an image and symbol of the Brussels folklore, the joy of the inhabitants and their capacity of self-mockery. Manneken Pis, as we know, the most faithful living and oldest citizen of Brussels. For the Manneken-Pis, the homeland is the corner of the Incubator and Oak Street in Brussels. It was Burgundian under the Dukes of Burgundy; German U Maximilian; Spanish under Charles V; beggars under the conditions; Austria under Maria Theresa; Republican in 1794; French under Napoleon; Almost Dutch under William; Belgian under Leopold; and we never saw him happier than today.
