Hey all! My wife and I just visited prague over the week of Christmas and really enjoyed our time in this extremely beautiful city! I did quite a bit of research before we went and we had a pretty diverse itinerary. I've just written a bit about some of our favorite things we did while in the city, which you might find helpful in planning your own trip. I've also marked a few spots of note on a google map which I'll link to here as well. Hope this helps in your travel prep and let me know if you have any questions!
