St. Paul is celebrating the legacy of the state's first black architect. Mayor Randy Kelly proclaimed today Cap Wigington Day. Wigington is best known for his work in the City Architect's office as a draftsman and architect from the twenties to the forties. Wigington designed public schools and other municipal buildings that continue to define the city's landscape. But some of his most creative work was designing ice castles for the St. Paul Winter Carnival. The Minnesota Historical Society has just published a new book about his contributions to St. Paul. Paul Larson is the co-author of "Cap Wigington: An Architectural Legacy in Ice and Stone." Larson says when Wigington moved to St. Paul in 1914, African American architects were very rare.
