Among the most significant works are Johan Philip Lemke's ten battle paintings in Karl X Gustav's Gallery, which Tessin the Younger described as 'full of life, spirit and fire.' These include depictions of the wars against Poland and Denmark in the 1650s, notably the March Across the Great Belt in winter 1658, the risky ice crossing that led to the Treaty of Roskilde. The Great Staircase, celebrated in Erik Dahlberg's Suecia Antiqua et Hodierna, remains one of Scandinavia's finest Baroque staircases, adorned with Millich's sculptures. The Ehrenstrahl Drawing Room and Hedvig Eleonora's State Bedchamber preserve early Baroque interiors of the 1660s and 1670s. Lovisa Ulrika's Green Antechamber exemplifies the French-inspired Rococo redecoration of her era. The Drottningholm Court Theatre, built in 1766, preserves its original wooden stage machinery, still manually operated to produce storms, rolling waves, and dramatic transformations. The theatre's collection includes original stage sets, dressing rooms, scenery, and an auditorium seating 400 spectators. The Chinese Pavilion contains an preserved ensemble of architecture, interior decoration, and collections representing chinoiserie taste. The French formal garden holds the world's largest collection of sculptures by Adriaen de Vries, acquired as booty from Prague and Fredriksborg Palace.
