We found this one after a visit to the Viking Ship museum in Roskilde. The cache is in a nice spot near some old half-timbered houses, and worth a visit. Given the cold and chilly weather, it was a good incentive to keep us outside a little longer.
(Unfortunately the rest of geocaching activities on the weekend were less successful. On Sunday we tried for a couple Swedish caches, but failed to find either, hampered by building works and locked gates. Back in Denmark we had the final option of a cache at Kronberg Slot, in Helsingør, but running out of time to catch the train we only got within a frustrating 300ft of it.)
