We truly enjoyed our tour of the Molen De Adriaan Museum! We visited on a weekday and had a guide all to ourselves. I would assume that they are busier during weekends. Unfortunately, we did not get to actually see the wings turning - apparently that happens usually on weekends.
The tour begins with a short video and then proceeds up the stairs and into the windmill, stopping on many levels as the guide explains the physical workings of the windmill and the jobs of the people who worked there. The original windmill was destroyed by a fire - the one you see is a reconstruction, but is a complete and working reconstruction. As a result of its newer construction it is quite clean inside (we understand some of the old ones are dusty and loaded with cobwebs).
During one of the final stops inside the windmill, you are taken to a room full of beautifully made wooden models showing the inner workings of many different types of Dutch windmills.
Our guide was very knowledgeable and always willing to answer questions. In addition, from a high vantage point, she gave us a visual tour of Haarlem and its history!
There are MANY stairs - get your climbing legs on and prepare for a delightful tour!
