What is "staerekassen"

Stærekassen ( lit. "The Starling Nest Box"), also known as Ny Scene (English: New Stage) 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.
