today Istanbul has a new attraction for young visitors, both foreigners and locals: a Dolphinarium. It was built by world famous Moscow Dolphinarium and opened in Eyup district just on the shores of the Golden Horn. The Municipality says that it's the "biggest dolphins show center in Europe". It has souvenir and toys shops and there will be marine biology classes for the youngsters too. Kids will also have a chance to swim with the dolphins.
The entrance is 20 Turkish Liras. I'm planning to visit it soon.
