A lovely café with delicious cappuccino and cake. In the village, beautiful old houses, but otherwise, more like—well, a place!

The whitewashed building consists of three wings enclosing a courtyard. Among the sights worth seeing are the preserved Baroque castle church (Danish: Gråsten Slotskirke) from 1699 and the castle park, laid out in 1700. The chapel and the castle park can be visited from April to October, when the royal family is away. Margrethe II and her family usually stay at Gravenstein Castle between mid-June and early August. Traditionally, the royal family arrives on the yacht Dannebrog, which is moored in front of Sønderborg Castle during the holiday weeks.
