A Warehouse of the 16th Century in Pisa, Italy

Architect Whitney Warren Jr.'s watercolor study documents Renaissance commercial architecture along the Arno River. The elevation drawing shows a symmetrical brick façade with paired arched openings and green wooden doors, characteristic of Pisa's merchant warehouses. Warren's measured approach—including the detailed cross-section and roof plan above—reflects late 19th-century architectural practice: careful historical documentation through precise rendering. The notation and sketched additions indicate working drawings for publication or reference, typical of American architects studying European precedents during the Gilded Age revival period.
