This 19th-century mansion, situated in Baltimore’s Mount Vernon district, has been part of The Walters Art Museum’s collection for years. However, it recently re-opened after a multi-year restoration that changed the entire visitor experience. In recent years, new scholarship came to light that offers a more comprehensive history of the house, including its ties to Baltimore and some of its inhabitants, who were enslaved people. The 1 West App is multi-vocal, interpreting multiple strands and layers of history and allowing visitors to explore the house on their own terms, switching through themes and eras as they move from room to room. Augmented reality adds to the experience, as certain parts of the house come to life.
