The Society's main focus is maintaining the 1901 Shiloh House, the home of Zion's founder, Dr. John Alexander Dowie. The Society maintains a museum collection in Shiloh House. Artifacts of the period, many the personal property of the late Dr. and Mrs. Dowie, are on display. The Society continues to build on its collection through donations of photographs, documents, and artifacts by both past and present Zion residents.

The house offers exhibits and tours.
