On the ground floor there is a shop where you can buy tickets, coffee, tea or bottled water and cookies, mill souvenirs, postcards and printed information about windmills and De Adriaan. On the semi round background you can see the Panorama of Haarlem around 1800, being painted by Chile Braat.
The 1st floor has educational and cultural functions. Here audio-visual presentations are running continuously. About Mills in general or Molen De Adriaan specifically. Always well received is the river Spaarne video. It's as if you travel on the river and from the water looking at the most beautiful places and interesting buildings along the banks. The first floor can be rented for marriage ceremonies, dinner parties, business meetings, training sessions, including catering.
On the 2nd floor you can find a permanent exhibition about how windmills work in general and the different types of mills for grinding different materials, sawing wood and pump up water from the polder.
On the 3rd floor you find a large model of Molen De Adriaan (see if you can point out where are you in the windmill), showcases of the materials ground in De Adriaan over a period of 150 years and a handmill where you can try to grind some grain manually yourself.
