Castles full of stories
Every castle and country estate in the Region is unique they are beautiful places full of stories that give character to the landscape. During the Golden Age, wealthy city dwellers and noble families built their summer residences along the inner dune ridge, as green oases away from the bustle of the city.
That rich history is still tangible today, not only in the magnificent houses and historic interiors, but also in the surrounding landscape gardens and parklands. Curious about the stories behind the castle walls?
