Copenhagen, Denmark’s capital, sits on the coastal islands of Zealand and Amager. It’s linked to Malmo in southern Sweden by the Öresund Bridge. Indre By, the city's historic center, contains Frederiksstaden, an 18th-century rococo district, home to the royal family’s Amalienborg Palace. Nearby is Christiansborg Palace and the Renaissance-era Rosenborg Castle, surrounded by gardens and home to the crown jewels.
