The Museum of Ramapough Native Indian Arts is a cultural center for artwork display, a monument of collective memories, and a portal to sacred territory, known as Split Rock. Sitting at the Ramapo Ridge, a carved staircase along the topography subtly invites visitors to step on to their journey. In the sunken courtyard, scattered rocks are presented under the light as a preview of the spiritual experience ahead. In the center atrium of public gallery space, visitors will return to the moment on a different hierarchy to embrace Ramapough values. The private gallery resembles the same architectural elements. However, it indicates a fully different story that becomes a vessel of Ramapough tribal memories. The structure made by rammed earth and steel carries the sensitivity of Native American construction, while implicitly presenting a pair of galleries for native cultures through inverse languages.
