Discover the Historic Mill-Rae House

The historic Mill-Rae House, built in 1890, was the home of suffragist Rachel Foster Avery and her family. The house was designed by Minerva Parker Nichols, the first woman in the United States to establish her own architecture practice. Located in Somerton, Philadelphia, the house became an important gathering place for leading suffragists who campaigned for national women’s voting rights. It also hosted the planning of exhibits and conventions for the 1893 World’s Columbian Exposition, as well as the creation of a pension fund for Susan B. Anthony—who was a close friend and mentor of Avery, often visiting the house during her activism.

This project was one of Nichols’ first major commissions, helping her establish a national reputation and laying the groundwork for future architectural work. Uniquely, Mill-Rae served a dual purpose: as a private residence for the Avery family and as a public space for women’s activism. In an era when spaces for such gatherings were scarce, the historic house provided a rare environment for women’s organizations to meet and organize.

Constructed using local schist and other materials, the house features a Shingle Style design, reflecting the architectural trends of Pennsylvania in the late 19th century. Its location on the outskirts of Philadelphia was a strategic decision to be close to train connections, offering a peaceful escape from the city.

Today, the house stands as the foundation of Cranaleith. It is used for day retreatants, overnight guests, small gatherings, and house tours during programs/events. Architectural historian Molly Lester continues to inform the world about the legacy of Minerva Parker Nichols through research, documentation, engaging presentations, and digital media.
