Museum Without Walls – Easton, PA. The National Canal Museum interprets the history and culture of canals as well as the science and technology behind their building, through exhibits and hands-on activities. Van Sickle & Rolleri is working with the museum to develop concepts for a new outdoor exhibition space. In the new outdoor exhibition space, children and adults can harness a mule, steer a canal boat, and engage in activities that help them learn how canals were built. The outdoor exhibition space will be located on the museum property in beautiful Hugh Moore Park, a 520-acre City of Easton park nestled between the Lehigh Canal and Lehigh River.
