Visit the Wagner to explore our historic site and museum collections, including minerals, fossils, shells, insects, taxidermy birds and mammals. You can explore on your own or use one of our themed scavenger hunts, drawing or coloring activities to guide you. You can also learn about the construction of our National Landmark Building, through an exhibit illustrated by photographs and materials from the archives, and through our architecture scavenger hunt designed for history buffs. Afterwards, stop by our gift shop and pick up a geode to crack open, polished crystals for your collection, a vintage tea towel or your own copy of Historic Landmarks of Philadelphia!

At 4PM join us for a presentation in the Lecture Hall followed by a guided walk through the museum, highlighting the architecture and a few of the most intriguing specimens—including dinosaur bones and the cabinet of human evolution. The tour is designed in collaboration with Girard College, our neighboring National Historic Landmark, whose founder Stephen Girard inspired William Wagner to build his own educational institution.

Celebrate International Day of Monuments and Sites at Stenton, a National Historic Landmark, with a special tour. Featuring collections objects, made, used, and owned, inherited, and stewarded by women from the 18th to the 20th centuries, this Curator’s tour builds on the longstanding theme of “Deborah, Dinah, and the Dames” to focus on women’s lives at Stenton.




The sandstone sculptural group Old Mortality and his Pony greet visitors daily to Laurel Hill East, establishing the cemetery’s place as a unique outdoor sculpture garden. Look beyond this impressive work and you’ll find many other breathtaking monuments, some of which were exhibited as artworks before their placement in the cemetery. Who were the sculptors and how did they shape our final view of those now resting peacefully beneath richly carved or poured materials? Funerary art can reflect the departed and the times they lived in. This tour will showcase Laurel Hill East as both a sculpture garden and a place of remembrance.
