Architecturally, the fort has a very well preserved 16th-century central keep with two five-story towers at opposite corners. The interior of the court is also well maintained and contains fine antique furniture, oriental objects, and painted ceilings, mainly dating from the 17th and 19th centuries.
Today, the castle and surrounding grounds, including a national collection of daffodils, are owned by the National Trust for Scotland and are accessible to the public for tours throughout the year. The castle can be rented for weddings and indoor or outdoor events. An old Pictish monument known as Rodney's Stone can be seen on the castle grounds.
