The Royal Baths (Łazienki Królewskie) is the largest park in Warsaw, Poland covering 76 hectares. The park was originally designed in the 17th century for Stanisław Herakliusz Lubomirski but was acquired by King Stanisław August Poniatowski in 1764. Under the King's reign, the classicist-style gardens and buildings were developed by several architects and designers. Many of the park's buildings were damaged during World War II but have since been reconstructed. The park remains a popular destination today and contains several notable structures like the Palace on the Water and Ujazdów Castle.
