Pacific Science Center

Step beneath Minoru Yamasaki's arches at Seattle Center, where Pacific Science Center fills his 1962 World's Fair pavilion with IMAX theaters, a Laser Dome, dinosaurs, butterflies and hundreds of hands-on exhibits. The building became a City of Seattle landmark in 2010.

Frequently asked questions

Pacific Science Center is at 202 2nd Ave N in Seattle, on the southwest corner of Seattle Center in the Lower Queen Anne neighborhood. The Space Needle is less than 0.1 mile away.

Pacific Science Center has two IMAX theaters, which makes it one of only a few places in the world with more than one. The first opened in 1979 in the former Eames theater, built for the 1962 World's Fair.

Minoru Yamasaki designed the complex as the United States Science Pavilion for the 1962 World's Fair. The design brought him international fame, and he later designed the World Trade Center in New York.

Yes. Pacific Science Center was designated a City of Seattle landmark in 2010 and is landmark number 347, recognized by the Seattle Landmarks Preservation Board.

Hours, ticket prices and parking details change, so check Pacific Science Center's official website for current information before visiting.

The full guide

Pointed white arches rise above courtyard pools at the southwest corner of Seattle Center, framing the entrance to Pacific Science Center. This nonprofit science museum at 202 2nd Ave N in Lower Queen Anne fills the pavilion Minoru Yamasaki designed for the 1962 World's Fair. More than a million visitors a year pass through its doors, and the complex has been an official City of Seattle landmark since 2010.

From World's Fair Pavilion to Science Center

Picture the grounds of the Century 21 Exposition, where these buildings opened as the United States Science Pavilion, home to the World of Science, one of the fair's five theme areas. The pavilion stood at the southern end of the fairgrounds, west of the Space Needle, and its soaring white arches made it easy to spot.

Once the fair closed, the pavilion reopened in 1962 as Pacific Science Center. For decades the organization leased the land and buildings for just $1.00 a year, until 2004, when the title passed to the Pacific Science Center Foundation and it took formal ownership.

Pause at the entrance fountains, which have their own claim to fame as a backdrop in the Elvis Presley film It Happened at the World's Fair. Fans of midcentury Seattle can stand in that very courtyard today.

Yamasaki's Famous Arches

Look up at the design that earned Minoru Yamasaki international recognition and a place on the cover of Time magazine. He went on to design the World Trade Center in New York City, and the arch shapes you see here became a recurring motif in his later work.

Walk along any of the buildings and you will notice the walls are made from many pre-cast concrete slabs that join to form the pointed arches. The complex covers 7.1 acres, and its courtyard pools and arches remain one of the most photographed corners of Seattle Center. Plans announced in 2025 call for renovating the courtyard, tying it more closely to the rest of the Seattle Center grounds and improving public access.

Sonic Bloom

Just outside, five flower sculptures about 33 feet tall rise near the museum. Seattle artist Dan Corson created Sonic Bloom after the center issued a 2013 call for public art that showed off solar energy, and he drew on the Australian firewheel tree for the design. Solar panels in the flower heads generate electricity, so the flowers hum as you walk up and glow once darkness falls.

What Fills the Eight Buildings

Today Pacific Science Center spreads across eight buildings, so give yourself room to wander. Highlights include:

  • Two IMAX theaters, a rare setup that few places in the world can match
  • The Seattle Laser Dome, one of the largest laser theaters in the world, home to laser light shows
  • A planetarium
  • A tropical butterfly house
  • A dinosaur exhibit, first installed in 1990
  • Hundreds of hands-on science exhibits, plus rotating traveling and temporary shows

IMAX and the Laser Dome

Catch a film where Pacific Science Center's first IMAX screen opened in 1979, converted from the Eames theater. That room was originally built to show a multi-screen IBM film during the World's Fair. The Laser Dome has a backstory of its own, starting life as the Spacerium, a domed theater built for a wide-angle film voyage through space.

Pieces Left From 1962

Only a few original fair exhibits survive, so keep an eye out for the Lens and Mirror Machine and a suspended model of the moon, both carried over from the exposition. The fair's famous illusion ramp, where buildings were deliberately constructed at a tilt, was recreated in the late 1990s.

Decades of Live Demonstrations

Live science runs deep here. Dixy Lee Ray directed the center for many years before she became governor of Washington, and she also hosted a science program for schoolchildren on Seattle PBS station KCTS-9, which helped build the center's audience among young viewers.

In the 1970s, guides in orange jackets, nicknamed "OJs," ran demonstrations throughout the museum. The math floor featured a large exhibit originally built for IBM at the New York World's Fair, including a probability machine that sounded an alarm before releasing a bin of balls, and it stayed until around 1980. Other buildings held a full-size lunar module mockup, a replica First Nations longhouse and a working hydraulic model of Puget Sound.

The 1980s brought rapid growth under executive director George Moynihan, hired in 1980 from Berkeley's Lawrence Hall of Science. A 1984 exhibit, China: 7000 Years of Discovery, raised the center's national profile. Traveling robotic dinosaur shows later in the decade paved the way for the permanent dinosaur display, while Kids Works, Body Works, an animal area and a tide pool opened in the same era.

Programs Beyond the Museum Floor

Pacific Science Center keeps busy year round with programs for every age. Look for youth and teen programs, summer camps at locations around Puget Sound, science-themed events for adults 21 and over, and research weekends.

The Science On Wheels vans bring hands-on lessons to schools across the Pacific Northwest, and a dedicated staff team supports teachers. In Bellevue, the center partners with the City of Bellevue on the Mercer Slough Environmental Education Center, which teaches wetland ecology, nature awareness and environmental stewardship.

Ownership is also shifting: in 2026, part of the museum was sold to Center Art LLC, a company associated with the owners of the Space Needle.

A City Landmark Since 2010

The Seattle Landmarks Preservation Board recognizes Pacific Science Center as City of Seattle landmark number 347. The 2010 designation, made under ordinance 124932, protects one of the most distinctive pieces of the 1962 fair, and the building joins a cluster of other designated sites on the Seattle Center grounds.

Planning Your Visit

Head to 202 2nd Ave N, at the southwest corner of the Seattle Center campus. Ticket prices, current hours, show schedules and parking details change, so check the museum's official website before you go.

Leave time for both the exhibit halls and a screening, since the IMAX theaters, Laser Dome and planetarium each run their own programs. Then linger in the courtyard after dark, when the Sonic Bloom flowers light up.

Landmarks Steps From the Arches

Few museums sit closer to so many designated landmarks. Within a few minutes' walk of Pacific Science Center, you can reach:

  • The Space Needle and the Horiuchi Mural, each less than 0.1 mile away
  • Seattle Center House (the Armory) and the Seattle Monorail, about 0.1 mile away
  • The Chief Seattle statue at Tilikum Place, about 0.2 mile away
