When a traveler is browsing in Kraton, then she/he should not miss The Water Castle or known as Tamansari, less than 1 Km west of Kraton. Just west of the Kraton, are the ruins, pools, arches and underground passages of the former pleasure gardens. It was built in 1758 by Sultan Hamengkubuwono I as a rest house and pleasure park for the Royal family. Tamansari means beautiful garden. It was badly damaged due to an earthquake in 1867. Some parts of it, for instance "Umbul Binangun" bathing pools have been restored.
