The Royal Danish Theatre (RDT, Danish: Det Kongelige Teater) is both the national Danish performing arts institution and a name used to refer to its old purpose-built venue from 1874 located on Kongens Nytorv in Copenhagen. The theatre was founded in 1748, first serving as the theatre of the king, and then as the theatre of the country. The theatre presents opera, the Royal Danish Ballet, classical music concerts (by the Royal Danish Orchestra, which dates back to 1448), and drama in several locations. (Wikipedia)
