On the Buda side of the island is the Alfréd Hajós Sports Swimming Pool, with an indoor pool 133.5m (37 yds.) long and two open-air ones of 33.5 and 50 m. ( 55 yds.); further on, in the centre of the island, are the Palatinus Outdoor Baths. The latter occupy an area of 17.5 acres and the three pools are filled with therapeutic water. In front of it we find the city's most beautiful rosegarden. Not far away, on the open-air stage next to the water tower, opera, operetta and ballet perform- ances are held. There is an open-air cinema which functions in the summer and nearby we find the Tennis Stadium.
