Vadstena Slott information
Lonely Planet review
Overlooking the lake, the mighty Renaissance castle Vadstena Slott was the family project of the early Vasa kings. The lower floors contain a small historical display. The furnished upper floors are more interesting, but only open during guided tours (in English mid-May to mid-September; call ahead for times); it’s worth going on one if only to visit the chapel, with its incredible 17-second echo!
