Walk Into the Secret Annex - Anne Frank House
Step through the actual swinging bookcase into the cramped, blacked-out rooms where Anne Frank, her family and four others hid for two years before betrayal. You climb the same steep stairs, see Anne's movie-star magazine clippings still pinned to her bedroom wall, and stand in the very space she wrote the diary in - the single most emotionally powerful 90 minutes anywhere in Amsterdam, and the one site a first-timer regrets missing forever.
