This is unquestionably Dudok's masterpiece. Built in 1928-1931, this building has wide international fame and features in many architecture textbooks. The building has a remarkable shape and feels like a combination of 'blocks'. It's built with specifically designed yellow bricks that have a slightly different size than traditional ones. Dudok is also responsible for the interior, the furniture, the decorations and even the font used. If open, visit the Dudok Dependance, a permanent overview of Dudok's life and work organised by Museum Hilversum. Every Friday and Sunday at 13:30, there is a guided tour through the building for €8.50. You can just show up, you don't need to register beforehand. The tour takes 90 minutes and is given in Dutch, but the guide will also talk in English upon request. It gives you the chance to view some of the rooms that are closed to the public, such as the marriage room and the mayor room. If the weather allows it, you will climb the 46 m tower for an overview of Hilversum and the surrounding area. There are special arrangements possible for groups. For bookings, call the listed phone number or inquire at the Museum Hilversum.
