Radisson Blu Royal Astorija Hotel, Vilnius

Gediminas Castle Tower

Gediminas Castle Tower is less than a kilometer from the hotel and named for a 14-century Lithuanian grand duke, can be seen from its hilltop perch just about everywhere in Old Town. The tower is the only remaining part of the Upper Castle and houses a museum. Climb to the top of the hill, or ride the funicular to the top for the most spectacular views of the city. For an even better view, go to the observation deck on top of the tower.
