Christiansborg Castle (Christiansborg Slot)
The fortress constructed by bishop Absalon in 1167 was reconstructed repeatedly over the years to this current form, which was completed in 1928. The castle is now used as a state guesthouse. Underground ruins of the 12th century fortress and a racing stable, features of the original castle, and other exhibits are open to the public.
