Wilmette-Kenilworth Patch has a fascinating look at the former home of architect / developer Benjamin Marshall in Wilmette. According to the Patch article, the home was "perhaps the most opulent mansion ever built on the North Shore." Perhaps not. A number of homes would vie for that title, including the Schweppe Mansion, built by the president of Marshall Field's as a wedding gift for his daughter Laura on her marriage to Charles Schweppe.
Whether or not the home merited its superlative, however, few would doubt that it stood on the most spectacular site on the North Shore, as you can see from the aerial view above and the photo below.
