Brønnum House is a richly decorated 1860s apartment building situated adjacent to the Toyal Danish Theatre's Stærekassen extension and the Harsdorff House on Kongens Nytorv in central Copenhagen, Denmark. It was constructed as one of the first new buildings when the former Gammelholm naval dockyards was transformed into a new residential neighborhood. Café Brønnum, frequented by actors from the adjacent theatre, was based in the building for more than 100 years. The homes of the wealthy Jewish businessman Martin Henriques and Bernhard Hirschsrpung on the first and second floor were both frequented by some of the leading cultural figures of their time. The building was listed in the Danish registry of protected buildings and places in 1995. The building is now owned by Karberghus. It houses a high-end cocktail bar on the ground floor and serviced offices on the upper floors.

Stærekassen, also known as Ny Scene is a theatre building annexed to the Royal Danish Theatre on Kongens Nytorv in Copenhagen, Denmark. It opened in 1931 to serve a dual purpose as an additional stage for the Royal Theatre and the first home of the new Danish Broadcasting Corporation. The colloquial name, which has now obtained official status, refers to the design of the stage tower in the shape of a box suspended above the street, and in the initial design proposals with a large round window high up as the dominating ornamental feature of the facade.
