Architectural Sketches: Loches and Tours

Francis Augustus Lathrop, the American architect and designer, documented his studies of French Gothic architecture during travels through the Loire Valley. This sheet captures preliminary sketches of ecclesiastical structures at Loches and Tours—finials, loches (window details), and a detailed bell tower elevation. Lathrop's precise line work and attention to ornamental vocabulary reveal the methodical observation that characterized late-nineteenth-century architectural practice. Such sketches served both as design reference and as training in the principles of Gothic proportion and detail, informing his subsequent work in American commercial and institutional architecture.
