The Theatre Museum is situated in the Old Court Theatre. Its collection describes Danish theatre history from the 1700s to the present day.

In 1767 the building next to Christiansborg Palace's riding facilities was arranged as a court theatre, the building that today houses the Theatre Museum.

The museum's collection consists of costumes, scenography, set models, paintings, drawings, and photos illustrate the history of the Danish Theatre from the 18th century to the present time.

The fall of Struensee

17 January 1772 the theatre was also center stage for a dramatic event. It was after a masquerade ball at the court theatre that Queen Caroline Mathilde and her lover Johan Friedrich Struensee were arrested and charged with lèse-majesté.

Struensee was imprisoned in the Citadel and Queen Caroline Mathilde placed under house arrest at Kronborg Castle in Elsinore. A few months later Struensee was executed by beheading, while Caroline Mathilde was banished to Celle in northern Germany.

Today, the Court Theatre is used for concerts, readings, exhibitions and talks. Visitors are admitted to the booths, the stage, and to the old dressing rooms.
