De Haar Castle

Rebuilt in 1892 with architectural flourishes that exceed those of typical medieval strongholds, it features 200 rooms filled with original furniture—rare among Dutch castles. The meticulously restored gardens alone span 135 acres, making them larger than Muiderslot's total grounds. Its 55-meter tower offers panoramic views that outclass Doorwerth Castle's river perspective for grandeur, and the castle attracts 200,000 visitors annually, cementing its status as the top castle for 2026.
