Are you ready to visit the Weldon Spring Site? Although the interpretive center has been closed to in-person visits since 2020, we are open to the public via virtual programs. We’re here to support your STEM curriculum at all grade levels and are ready to connect you with experts in many fields. Our interpreters have been hard at work creating and presenting programming for schools, community groups, and the public — all in a virtual environment.  Contact us at WSInterpretivecenter@lm.doe.gov or 636-300-2601 to set up your virtual program.

At the Weldon Spring Site, we welcome you to hike along the Hamburg trail and enjoy the native plant gardens with outdoor benches and picnic tables. While the stairs to the top of the disposal cell are closed for repair, the pathway surrounding it is still open. 

We will continue to update our communications, if anything changes in the status of our interpretive center, and we look forward to the time when we can safely welcome our visitors back inside. We ask that guests follow the updated federal guidance related to social distancing, provided by the Centers for Disease Control and Prevention.

See you (virtually!),
The Weldon Spring Site Team

Weldon Spring Site Interpretive Center

Construction on the U.S. Department of Energy (DOE) Office of Legacy (LM) Weldon Spring Site New Interpretive Center began in May 2019 and was completed in 2021 under the guidance of the U.S. Army Corps of Engineers (USACE) St. Louis District and LM leadership. The new facility features four classrooms each of which seats 40 people, an auditorium seating 80 people, a 4,500 square foot exhibit gallery with newly fabricated exhibits, and administrative office space for employees. The design of the facility adheres to the Guiding Principles for Sustainable Federal Buildings (Guiding Principles), established by the U.S. Environmental Protection Agency (EPA) in 2006. These Guiding Principles are the federal equivalent to the U.S. Green Building Councils LEED (Leadership in Energy and Environmental Design) certification, a globally recognized symbol of sustainability achievement and leadership.
