If you are in Amsterdam, you must visit the Anne Frank House, which is located on the Prinsengracht Canal. It was in this "Secret Annex" that the young Anne Frank wrote her world-famous diary while hiding in occupied Holland.
Visitors are allowed to visit almost all rooms in the cramped annex, where eight people hid for two years (1942-1944), bravely assisted by four of Otto Frank's employees. It is a stirring, solemn, thought-provoking experience.
Buy your tickets online - it will allow you to bypass the blocks-long line and enter immediately through a side door.
After visiting the house, stroll through the pretty streets surrounding the Prinsengracht Canal. Anne Frank's old neighborhood has developed into an upscale area with inviting cafes and boutiques. Main sights include the Westerkerk Church (above, whose ringing bells were mentioned in Anne's diary) and the Nine Streets shopping district.
