Personally I'm thinking of Adelaide, Australia. It might not be the strongest example in the world but here is a photo that shows it off https://m3.efront.digital/wp-content/uploads/2020/10/iStock-...

Shiny modern towers next to historical buildings. All of the buildings in this photo are from a range of times and design styles. I think if you took any one of these buildings and made the rest look similar, the aesthetics would be degraded.
