No icon represents Seattle quite like the Space Needle. Built in 1962 for a futuristic World's Fair, it now sits above the Seattle Center, the perfect emblem of a city that has, then and now, embraced science and technology. Though the base has renovated ticket booths and gift shops, the elevator ride hasn't changed much in 50 years. Up top, there are observation decks at 520 feet above the ground, with indoor and outdoor viewing areas, and a revolving restaurant just below. Reservations are advised, and once there, leave time to wait for a window-side table for the full experience. The view is spectacular day and night, with distant mountains to spot in almost every direction.
