Binnenhof
The Binnenhof is a Gothic palace complex that has been the center of Dutch politics since 1446, making it the oldest parliament building still in use worldwide. The complex includes the famous Hall of Knights (Ridderzaal) and overlooks the picturesque Hofvijver lake. Featuring 13th-century Gothic architecture, historic courtyards, and fountains, it's the heart of Dutch democracy and an iconic must-see.
