As if a spaceship had landed: in 1962, Seattle hosted the World’s Fair, and just as 80 years earlier in Paris, the US city has retained its iconic tower. The Space Needle is quite literally the highlight of the site. Be sure to go up the viewing tower to enjoy the view of the port and sky scrapers and as far afield as the Rocky Mountains. The World’s Fair site has even more to offer, though: it houses more than 30 sports, educational, and cultural institutions, including the Pacific Space Center and the Museum of Pop Culture. Take a ride back to the city centre with the Seattle Center Monorail, an elevated train that still sports its charming 1960s design.
