Netherlands: Medemblik

Medemblik was a prosperous trading town, when, in 1282, Floris V, Count of Holland, successfully invaded West Friesland. He built several fortresses to control the region. Medemblik is best known in Europe for its sailing events. Medemblik further has a picturesque small innercity with many houses from the 17th and 18th century, two big churches, an old orphanage, a town hall and, of course, castle Radboud, which is just at the border of the innercity.
