The National Museum is housed in an 18th-century Rococo palace - formerly the home of the Crown Prince of Denmark - with a main hall so grand it's often used as a concert venue. The historical exhibits span from the Viking period to today, and are numerous enough to fill multiple days of exploration; those short on time should head straight for the second floor to the prehistoric section, which has the largest collection of Inuit art and culture in the world. Other highlights include bog-preserved artifacts from the Early Bronze Age, the Royal Collection of Coins and Medals, and the Children's Museum, which breaks down the history into more easily digestible bites. Admission is free.
