I especially recommend visiting St. Petersburg during the summer. It's on that same latitude so you get nights that don't go dark and the whole city celebrates.

I especially recommend visiting St. Petersburg during the summer. It's on that same latitude so you get nights that don't go dark and the whole city celebrates. They're called "White Nights" and there's a "White Night Festival"[1] but really, the fascinating part is how the whole city (or at least the city center) comes alive during those nights. It's absolutely beautiful. [1]: https://en.wikipedia.org/wiki/White_Nights_Festival https://en.wikipedia.org/wiki/White_Nights_Festival
