QUESTION: Mill

Because Brouwershaven's mill is on the town's ramparts, you can see it from afar. Built in 1724, grain was still ground here until 1954. Restoration began a few years later and found traces of an old mill that stood on the same spot. The last restoration took place in the 1960s by the millwright J. van den Hamer. So the little mill “windlust” has apparently been good publicity! Of course, this mill also has a name. Which one is that? You can find that on the cap of the mill. 
Question 4: On which dike is this mill located? Write down the last letter.
