Inside of St. Vitus Cathedral
What a magical place! You can enter the cathedral without paying but if you want to truly make the most out of the spectacular stain glass windows and glorious epitaphs then it's 250 crowns. Would highly recommend going up to the top of the tower, however this is another 150 crowns and it's a very long, steep spiral staircase, the view from the top is quite simple breathtaking!
