We also offer our members Delaware’s best fireworks. This members-only event is held each year, two Fridays in summer. It is a spectacular evening of family fun for a reasonable price.

New programs connect you to a community of members who share your interests. Members can explore our walking tours, visit the E. I. du Pont Residence and garden, attend lectures, and enjoy our annual antique car show and craft fair. All for free!

If you have children or grandchildren ten years of age and younger, join our Powder Keg Kids club. Throughout the year you can participate in hands-on science programs at Science Saturdays, Invention Convention, NatureFest, and Hagley Youth Leadership programs. All for free!

Membership dues at all levels support Hagley Museum and Library’s year-round family programs, our 235-acre site along the Brandywine River, and museum and library collections care and access.
