Someone commented, the distorted image looks like a pizza. However, that does not mean it is a city in Italy.
The prominent building appears to grow out of the less prominent buildings forming the circle (or pizza crust) in the distorted image. Approaching this city from the sea the Lutheran Cathedral does indeed dominate the skyline and is the best clue in identifying it. The city is Helsinki
Congratulations to Jackie (@jackiesjourneys), Atul (@pixodentist), Dave (@travelling_dave) and Tim (@timofnewbury) who identified the city as Helsinki.
This week the distorted city may be a little more challenging. It is fairly easy to identify which region of the world the architecture comes from. Identifying the city may prove a little more difficult.
