Gripsholm Castle was begun in 1537 by King Gustav Vasa as a fortified stronghold on an islet just outside the town centre of Mariefred. Its four round brick towers, courtyard cannons, and drawbridge make it one of Sweden’s best-preserved Vasa castles.
Duke Karl’s Chamber and Gustav III’s Theatre
Inside the walls, four centuries of interior history come together. Duke Karl’s Chamber from the 16th century retains its Renaissance painted ceilings and wood panelling, while Gustav III’s round theatre from 1781 is built inside one of the castle towers with original stage machinery.
The Swedish National Portrait Collection
The castle also houses the Swedish National Portrait Collection, founded in 1822 and today comprising more than 5,000 works. Each year the collection adds a new portrait of Honor depicting a notable Swede.
Visits, season and castle grounds
During the summer season from May to September the castle is open daily, with weekend openings continuing through autumn until November. The surrounding castle park, apple orchard, herb garden, and lakeside promenade are open year-round.
