A three-year, $10.4 million transformation, overseen by Marks, Thomas Architects for The Walters Art Museum has rejuvenated its nearby annex, a Greek Revival mansion at 1 West Mount Vernon Place. Opened in June, the newly climate-controlled interiors gleam with restored plaster panels painted with fleur-de-lis reliefs; ornate Baccarat-style chandeliers; a grand spiral staircase; and a Tiffany stained-glass skylight.

Against this rich backdrop, pieces from the Walters’ collection, including 19th-century paintings, sculpture and decorative arts, blend perfectly on the first floor, which also showcases new works by ceramicist Roberto Lugo. Ceramics are displayed on the second floor, which is home to changing exhibits and community art projects. In a “maker space,” visitors can pursue their own artistic endeavors.

Says the Walters’ executive director Julia Marciari-Alexander, 1 West Mount Vernon Place “represents the next step in the museum’s evolution. It’s a place where we can collaborate with the public to create exceptional experiences.” thewalters.org
