The Saint Louis Science Center traces its roots to the Academy of Science of St. Louis, founded in 1856 as the first scientific organization west of the Mississippi River. In 1959, the Academy created the Museum of Science and Natural History in Clayton’s Oak Knoll Park. When the Metropolitan Zoological Park & Museum District (ZMD) was formed in 1971, the Museum of Science and Natural History became a member, independent from the Academy, which continues to operate as a separate entity to this day. 

The Museum then outgrew the facilities at Oak Knoll Park in the mid-1980s and, in 1984, the Museum acquired the James S. McDonnell Planetarium from the City of St. Louis. After extensive renovations, the Planetarium reopened in 1985 as the Saint Louis Science Center.   

Following a $34 million expansion to construct the current main building on Oakland Avenue, the Science Center opened November 2, 1991, in its larger footprint including the five story OMNIMAX® Theater and a highway-spanning connection bridge. The Science Center added the EXPLORADOME in 1997 in order to provide an additional space for large traveling exhibitions. With the popularity of the EXPLORADOME, the Science Center took action to create a permanent exhibition space. In October, 2011 Boeing Hall opened dedicating 13,000 square feet of exhibit space for traveling exhibitions.   

The Saint Louis Science Center was named a Smithsonian Institution Affiliate, the first in the St. Louis area in 2016. This title provides access of Smithsonian artifacts, traveling exhibits, and educational collaborations locally and nationally. 

The 50,000 square foot area previously used for the EXPLORADOME was renovated into GROW, an indoor/outdoor exhibit dedicated to the experience of the journey of the food supply from farm to fork. The agriculture exhibit opened to the public on June 18, 2016. 

The Saint Louis Science Center features more than 700 interactive exhibits in ten galleries, including GROW, Mission: Mars, Life Science Lab, Makerspace, Discovery Room, Ecology and Environment, Human Adventure, Structures, Liftoff and Experience Energy. In addition, guests can see science in action through Amazing Science Demonstrations at CenterStage, enjoy a thrilling film experience at the OMNIMAX Theater and gaze at the stars at the James S. McDonnell Planetarium.

The St. Louis Zoological Park, commonly known as the St. Louis Zoo, is a zoo in Forest Park in St. Louis, Missouri, United States. It is recognized as a leading zoo in animal management, research, conservation, and education. The zoo is accredited by the Association of Zoos and Aquariums (AZA). Admission is free based on a public subsidy from a cultural tax district, the Metropolitan Zoological Park and Museum District (ZMD); fees are charged for some special attractions. A special feature is the 2 ft (610 mm) narrow gauge Emerson Zooline Railroad with passenger trains pulled by Chance Rides C.P. Huntington locomotives that encircle the zoo, stopping at the more popular attractions.

The city purchased its first exhibit, the Flight Cage, from the Smithsonian Institution following the 1904 St. Louis World's Fair. After the zoo was established, new exhibits, areas and buildings were added through the decades to improve care of the animals, the range of animals and habitats shown, as well as education and interpretation

At an astounding 630-feet tall, the magnificent Gateway Arch remains the tallest man-made national monument in the United States. Its unique shape and stainless steel facade remarkably represent the history made in the city of St. Louis. An enclosed tram inside the Arch takes you to the top, where you will experience breathtaking views of modern St. Louis – up to 30 miles in each direction on a clear day. Along with the surrounding Jefferson National Expansion Memorial, the Gateway Arch opens up a world of history about how St. Louis served as the Gateway to the West for early settlers.

In 1947, the Jefferson National Expansion Memorial Association conducted a contest to create a structure that would commemorate Thomas Jefferson and those settlers’ expansion into western America. Renowned architect Eero Saarinen won the contest with his concept of a stainless steel arch. His vision was completed in 1965 when workers installed the last exterior shell piece of the Gateway Arch.

It cost $13 million to construct the Arch. The foundations extend 60 feet into the ground, and in its entirety, the Arch weighs 17,246 tons, including 900 tons of stainless steel. Built to withstand earthquakes and high winds, the monument may sway up to one inch in a 20 mile-per-hour wind.

Since its completion, other enhancements have been made to the Arch, including the addition of museum exhibits, a Grand Staircase and exterior lighting. Even today, projects to improve the Arch grounds are underway.
