Considering the Kinissi Palace in Thessaloniki?

Thermaikos Gulf by AndyRG
Thessaloniki is built next to Thermaikos Gulf. This avenue is a central one of the city. At the background, you can see the port. The central Aristotelous square is somewhere on the right of the picture (it can't be seen).
You can visit many interesting places, as the Arc of Roman emperor Galerius (303), Rotonda-Kamara, Eptapirgio, the Concert Hall, the Archaeological Museum -see my travelogue about it- the Byzantine Museum, the Museum of Modern Art, also the only museums in Greece about design and cinema etc.
