Pacific Science Center

The 1962 World's Fair, officially Century 21, gave Seattle its Space Needle, its monorail, and this building. The United States Science Pavilion was the fair's showcase of American science, and at the time it held the largest science exhibit in the country, drawing crowds through the summer of 1962.

When the fair closed that October, the pavilion did not go dark. The very next day it reopened as Pacific Science Center, a private nonprofit museum, making it one of the first institutions in the nation founded specifically as a science and technology center for the public. It has anchored Seattle Center, the old fairgrounds, ever since.

The pavilion was designed by the Seattle-raised architect Minoru Yamasaki, who would later design the World Trade Center towers in New York. For the fair he wanted something that felt uplifting and serene, and he gave the complex a set of delicate, pointed white arches over courtyards and pools of moving water.

Yamasaki called the look space gothic, a deliberate blend of the soaring lines of a Gothic cathedral with the optimistic, forward-looking spirit of the space age. Six white exhibit halls, patterned with fine parallel tracery, gather around the elevated central courtyard, and the arches remain one of the most photographed pieces of architecture in the city.

Inside, the museum is unapologetically hands-on, built for touching, testing, and asking why. Live science demonstrations run on a stage, exhibits invite you to experiment, and traveling shows bring in everything from dinosaurs to the human body.

The signature spaces have their own devoted fans. A large tropical butterfly house lets hundreds of butterflies flutter freely around you in warm, planted air. A planetarium projects the night sky, a domed theater hosts laser light shows set to music, and an IMAX screen shows science and nature films at giant scale.

The science center is one piece of Seattle Center, the seventy-plus-acre campus that the World's Fair left behind and the city turned into a permanent gathering place. Step out of the arches and the Space Needle is right there across the plaza, along with museums, theaters, fountains, and festival lawns.

That makes the museum an easy anchor for a day in this corner of Seattle. The monorail glides in from downtown, the Museum of Pop Culture and the Chihuly glass garden are steps away, and Pike Place Market and the waterfront are a short ride south.
