One of the unique churches which charms with its arcitecture. Not without reason it's listed in Unesco World Heritage List. Although it's not very convenient to take the photo next to it, as the square around the cathedral isn't very big. As mostly, it's better to do that from the distance.
Roskilde is a cosy and nice town, but there's nothing to compare with Copenhagen. Anyway, as every place is beautiful in its own way, Roskilde hides some pearls as well. Worth to see it!
