Taman Sari was the sultans' pleasure palace. Although seriously damaged by an earthquake in 1867, it has retained the old-fashioned charm of a spot devoted to relaxation and meditation. Behind the residence (the water palace, as the Dutch called it), an enclosed area comprises three bathing pools: one for women and children, one for concubines and one for the sultan. Do not miss the "underground mosque", actually a sort of atrium that was accessed via galleries and most probably used for some kind of religious service.
