Museums and exhibition buildings
With its subdued facade and entrance, this building for the Union of Diamond Workers (one of the first Dutch trade unions) symbolizes the power of the workers' movement. The well-proportioned front includes windows grouped in threes of equal size and constant width though of variable height. The staircase is bright and cheerful through the use of yellow brick and a rooflight. This stair, along with once boarded-up mural paintings by R.N. Roland Holst, was largely restored to its former glory when the building was recycled as a Trade Union Museum.
