There are high quality exhibitions and museums worth visiting. The paintings in them are very Turkish, and the landscape paintings are even more beautiful. There are also some interesting small objects, which are very good. It's not far from other scenic spots. You can plan your trip here.
The Pella Art Museum is facing the Bosporus Strait, next to the famous Palace Hotel. The appearance of the building is still a five-storey building with Roman style. However, it contains small objects of Turkey's local human society, remembering that the gallery is on the fourth floor. The gallery is small, but the paintings in it mostly show Turkish local customs, including Istanbul figure paintings, as well as Istanbul landscape paintings. Among them, the painting of the tortoise trainer seems to be the most famous one. The ticket seems to be 10 lira. As for the traffic, I came along Independent Street. I think I can take a tram to walk under the Galatay Bridge.
The Pera Palace Hotel, which used to be, is said to have retained its original look so far, and this insistence is particularly enjoyable. It's not only a hotel, but also a museum. It has the earliest elevator in Turkey and the car of the King of Sudan. It's very luxurious anyway.
