The Pacific Science Center is a nonprofit science museum located at the Seattle Center campus, originally built for the 1962 World's Fair. It is defined by its iconic series of six white arches designed by architect Minoru Yamasaki. The institution features the Tropical Butterfly House, which maintains a constant climate to support hundreds of live butterflies. Its campus includes two IMAX theaters capable of showing 3D digital and laser projections. Interactive galleries focus on subjects ranging from planetary science and physics to local regional ecology. The center offers rotating traveling exhibitions that frequently update throughout the year. It serves as a primary educational hub for STEM engagement in the Pacific Northwest.
The reflective pools located beneath the iconic white arches provide the classic architectural shot of the complex.
