The house was purchased in 1998 and used as the museum with changing exhibits before the barn was built. It is now interpreting an 1860's house. There are rare artifacts through out the house. There is also a small exhibit room upstairs.
The house is handicap accessible to the first floor only.
The house bathroom facility is not wheelchair accessible.
The barn is completely accessible with ADA bathrooms and kitchen.
The barn is used for changing exhibits, permanent local Civil War exhibit, meeting/event space, and climate controlled storage.
When the long-range plan for AAMI was developed in 1999, one of the objectives was to provide the proper storage environment with climate control for the museum’s collections. The primary action plan to fulfill that goal was to build a separate curatorial storage facility.
Some of the considerations included in the concept were maintaining the historic integrity of the property, the aesthetics of placing another building in proximity to the 1860 house, and the stated purpose of AAMI which is to preserve, exhibit, and interpret, items that will serve to illustrate the history of the Borough of Greencastle and Antrim Township.
The barn itself is an exhibit of German Bank barn architecture. The barn is completely air conditioned providing a constant temperature year round. The upper level provides exhibit, event, meeting and workshop areas. The storage area is located in the lower level.
The addition of the barn facility allows Allison-Antrim Museum to expand its programs and become more of an integral part of the Greencastle-Antrim community by strengthening its partnership with the school district and helping to increase the economic vitality of the area.
On August 30, 2017, Andy Stout, Greencastle native and Eastern Regional Director of The Archaeological Conservancy (TAC), and Bonnie Shockey, President & CEO, on behalf the board of directors of Allison-Antrim Museum, Inc (AAMI), signed a 99-year lease between TAC and AAMI, which transfers the care of the standing structures, within the Ebbert Spring Heritage Park & Archaeological Preserve, to Allison-Antrim Museum.
The property will become a dusk to dawn park.
