Łazienki Park, 00-460, Warsaw, Poland
The Water Tower, also referred to as the Reservoir, was constructed during the time of Stanisław Herakliusz Lubomirski. Its purpose was to collect water from nearby sources and transport it to the Palace via pipes. This circular outbuilding, also known as the Rotunda, Round Tower, or Reservoir, was designed to collect water for the fountains located in the Palace on the Isle and the terrace in front of it. In 1823, architect Chrystian Piotr Aigner gave the Water Tower its current architectural form, which was inspired by the 1st century BCE Tomb of Caecilia Metella in Rome. During the reign of King Stanislaw August, the Water Tower served as housing for royal servants. Today, it houses an exhibition on the building's history and the importance of water in the functioning of Lazienki.
