Loggia del Papa o dei Nobili, Siena

Architectural study by American architect Whitney Warren Jr. documenting the Renaissance loggia in Siena, Italy. The elevation drawing records the structure's three-bay arcade with Corinthian capitals, ornamental balustrade, and terracotta roof tiles. Warren's measured study includes detail sketches of decorative moldings and classical orders at right. Such documentation formed part of the Beaux-Arts tradition of architectural education through direct observation of historical buildings, establishing visual precedents for American neoclassical design in the late nineteenth century.
