Keep its story alive.

For more than two centuries, The Octagon has stood at the intersection of architecture and American history.

Designed by Dr. William Thornton, architect of the U.S. Capitol, this National Historic Landmark has witnessed defining moments in our nation’s story — and today serves as an active museum, gathering place, and home for conversations about architecture, design, preservation, and culture.

Caring for a historic building never stops. Your support helps the Architects Foundation preserve The Octagon and its collections, welcome visitors, and bring the building to life through exhibitions, educational programs, tours, and events.

A gift to The Octagon Annual Fund helps ensure this remarkable place remains preserved, accessible, and relevant for generations to come.

Help us care for the past while creating a place for new ideas, stories, and experiences.
