Rendering of Two Stone Lanterns, from the Castle in Amboise, France

Architect Whitney Warren Jr. produced these detailed studies of architectural ornaments during research for a restoration or design project at Château d'Amboise. The sheet presents multiple views of stone lanterns—traditional exterior fixtures—rendered in watercolor with careful attention to construction details, decorative lattice patterns, and three-dimensional form. Warren's analytical approach reflects the training of Beaux-Arts architects, who documented historical structures through measured drawing and comparative studies. Such architectural sketches served both as historical records and as design references for contemporary projects seeking to echo or complement period styles.
