The Academy of Natural Sciences has announced that its public museum in Philadelphia will permanently close on September 30, 2026, citing long-term financial pressures, higher operating costs, and lower attendance since the COVID-19 pandemic. While the museum galleries will close, Drexel University says the Academy’s internationally recognized research programs, scientific collections, and educational initiatives will continue.
Academy of Natural Sciences Museum to End Nearly Two Centuries of Public Exhibitions
A chapter in Philadelphia’s cultural history is coming to an end as the Academy of Natural Sciences prepares to close its museum after serving visitors for almost 200 years.
Drexel University, which has overseen the Academy since 2011, confirmed that the museum will permanently shut its doors on September 30, 2026. The announcement affects the public exhibition spaces that have welcomed millions of visitors over generations but does not signal the end of the Academy itself. Research laboratories, scientific collections, and environmental studies will continue operating from the same campus.
For many Philadelphia families, the museum has long been a destination for school field trips, dinosaur exhibits, and hands-on science learning. Its closure represents a significant change in the city’s museum landscape.
A Difficult Financial Decision
According to Drexel University, the decision followed an extensive review of the Academy’s financial outlook.
Museum leaders said attendance has remained below pre-pandemic levels despite efforts to attract more visitors through special exhibitions and educational programming. Combined with increasing building maintenance costs and operational expenses, those challenges made the museum difficult to sustain over the long term.
University officials emphasized that preserving the Academy’s scientific work became the priority.
Rather than continuing to devote substantial resources to operating public galleries, leadership decided to focus funding on research, specimen preservation, and environmental science programs.
Museum Will Close, Institution Will Remain
One of the biggest points of confusion following the announcement is whether the Academy of Natural Sciences itself is shutting down.
The answer is no.
Only the museum portion of the institution will close.
The Academy will continue to:
- Care for millions of scientific specimens.
- Conduct biological and environmental research.
- Support scientists and academic collaborations.
- Provide educational outreach programs.
- Preserve its archives for future generations.
Officials stressed that protecting these scientific resources was one of the main reasons behind the decision.
An Institution With Deep Historical Roots
Founded in 1812, the Academy is recognized as the oldest natural science institution in the Americas.
Its museum opened to the public in 1828, decades before many of today’s major natural history museums existed.
Over the years, the Academy became internationally respected for its contributions to:
- Paleontology
- Ornithology
- Botany
- Freshwater ecology
- Biodiversity research
- Environmental conservation
Its collections now include more than 19 million biological specimens, fossils, minerals, archives, and scientific records that continue to support researchers around the world.
What Visitors Will Lose
Although research will continue, the museum’s closure means visitors will no longer have access to many of its best-known attractions.
Among the exhibits that have defined the Academy experience are:
- Towering dinosaur skeletons in Dinosaur Hall.
- Historic wildlife dioramas.
- Live animal displays.
- Children’s discovery areas.
- Temporary science exhibitions.
- Fossil preparation demonstrations.
These exhibits helped introduce generations of young visitors to natural history and inspired many future scientists.
While Drexel says it hopes to create new opportunities for public engagement in the future, no replacement museum or exhibition plan has been announced.
Leadership Explains the Move
In their official announcement, Drexel University President Antonio Merlo and Board Chair Suzanne Biemiller acknowledged that closing the museum would be disappointing for many people connected to the Academy.
They said the decision followed careful consideration and was intended to ensure the long-term survival of the Academy’s scientific mission.
Leadership also noted that the Academy remains committed to public education and will continue exploring financially sustainable ways to share portions of its collections with the public in the future.
The announcement also confirmed a leadership transition, with Academy President and CEO Scott Cooper stepping down as the institution begins its next phase.
Why the Closure Matters
The museum’s closure extends beyond Philadelphia.
The Academy of Natural Sciences has played an important role in American scientific history for more than two centuries. Its collections have contributed to biodiversity research, environmental policy, and species identification across the globe.
For local residents, however, the loss is deeply personal.
The museum has been one of Philadelphia’s signature educational attractions, regularly hosting school groups, families, tourists, and community events. It also formed part of the city’s well-known museum district along Benjamin Franklin Parkway.
The closure reflects broader challenges facing museums nationwide as institutions continue adapting to changing visitor habits and financial realities after the pandemic.
What Happens Next?
The museum will continue welcoming visitors until September 30, 2026.
After that date:
- Public exhibition galleries will close.
- Scientific collections will remain protected.
- Researchers will continue using Academy resources.
- Educational and environmental programs will continue.
- Drexel University will explore new ways to share parts of the Academy’s collections with the public.
At this stage, officials have not announced whether another museum space or permanent exhibition will eventually replace the current galleries.
