Restrooms were located in the lower level. Tight spiral staircase with the lower level having a Dungeon atmosphere. We enjoyed the period paintings both on the walls and ceilings (some were breathtaking). The Castle has housed the Museum of National history (since 1878) with a collection that presents 500 years of Danish history. The furniture, Grand rooms, Knights armor and overall decorations transport you back to a time long ago. My only wish would have been to have more posted information/signage about what was in view. There is also a Church attached/next door which wasn't open to the public when we first arrived as there was a wedding. Opened up when we finished our Castle tour so we walked next door and spent some time there. Organ was playing so it added to the peaceful vibe and complemented the architectural beauty. It took us about 1.5 hours for Castle and Church although we didn't explore the grounds and the garden area in the back -so would recommend 2.5 to 3 hours for all. Saw a small Cafe. Service minded people were helping visitors with questions and ticket purchases. Really impressed by this Castle as well Hillerød.
