As others have already said, maybe it wasn't destroyed. The Empire had thousands of years to shape Solitude into their personal home-away-from-home and central fortress in Skyrim, and nothing says they didn't do that. Nothing says they did. There's just nothing said anywhere about any of it. Serana doesn't say what Solitude looks like, and apparently she saw it from faaaaaaar away. This is deliberately vague. There's no evidence to be had here.

In logic, when one makes a statement of "if [x] us true, it leads to contradiction [y]," that's called a Disproof. It means [x] isn't true. We use this as a tool to test propositions when we're not sure if they're true yet. You have to first show that [x] is true, then talk about contradictions.
