Academy of Natural Sciences closes Philadelphia museum as public-access plans remain unclear

The Academy of Natural Sciences in Philadelphia closed its public museum effective Sept. 30, ending regular visits to its galleries while its scientific collections and research continue. For residents and visitors, the immediate change is clear: the museum is closed, and the Academy has not announced a replacement gallery or a schedule for public science programs.

The effective closure date was Sept. 30, according to Drexel University, which is affiliated with the Academy. Billy Penn reported that the last visitors left on Sunday, Sept. 27. That distinction matters for anyone trying to understand when public visits ended: the institution's formal closure date was later than its final visiting day.

What access to the Academy's collections continues

The Academy says its collections, library and archives remain available for research and education. Its scientists will continue their work, and the building on the Benjamin Franklin Parkway remains in operation, housing collections, research and exhibit materials. Those commitments describe access for researchers and students; they do not establish a way for the general public to enter the former museum galleries.

The Academy identifies loans to exhibitions at other institutions as one way the public may encounter its collection materials. Its published guidance does not name receiving venues, dates or a replacement gallery. It also says it is evaluating what to do with exhibits and features in the former museum space, while original fossils and other scientific materials will remain preserved in its collections.

Drexel describes continuing work on freshwater ecosystems and environmental change, as well as courses, co-ops and fieldwork involving its students and Academy scientists. University President Antonio Merlo has said Drexel is committed to long-term stewardship of the collections and to their service to researchers, educators, students and the public. His statement does not specify a new public visiting arrangement.

Why the museum closed and who wants it reopened

The Academy says museum operating and upkeep costs exceeded what its revenue model could support after changes in public engagement following the pandemic. That is the institution's explanation for the decision. It says closing the museum allows it to direct resources toward its scientific collections, research and broader educational mission.

The decision has met public opposition. Billy Penn reported that approximately 200 people gathered outside the museum on Sept. 27 and marched to City Hall seeking its reopening. The gathering showed that the loss of gallery access has become a civic issue as well as an institutional decision.

In a Sept. 30 interview with PhillyVoice, Save the Academy organizer Sarah McAnulty said the group wants Drexel's board to disaffiliate from the Academy and wants an independent public process to decide its future. Drexel told PhillyVoice it had previously offered a path to disaffiliation, remained open to it and was continuing private discussions with the Academy. No agreement was announced in that reporting.

A proposed source of temporary support also remains part of the dispute. The Philadelphia Inquirer reported Sept. 25 that the William Penn Foundation offered to cover, for at least a year, the operating subsidy Drexel had provided, allowing time to examine longer-term options. Drexel said then that it had no proposal providing a permanent, sustainable path. The offer did not prevent the museum's closure.

What happens next for Philadelphia visitors

The Academy says it will communicate directly with members about their memberships and post updates on its website. It also says it is working with people and organizations holding private-event reservations. For the wider public, the unresolved questions are where collection loans might be shown, whether public science programming will resume in another form, and whether any plan will restore regular museum visits. The Academy's published guidance supplies no venues or timetable for those possibilities.

For now, the clearest distinction is between the institution's continuing scientific work and the end of ordinary museum access. Researchers and students retain access to collections for their work, according to the Academy, while Philadelphians who formerly visited the galleries have no announced replacement. Any change to that position would require a further decision and a public plan from the Academy or Drexel.
