One of the most famous areas in Florence is the Piazza della Signoria, the historic political centre of the city. This sketch depicts the south-eastern corner of the square which is dominated by two important buildings: on the left the Palazzo Vecchio (the Florentine town hall, also know as the Palazzo della Signoria); and on the right the Loggia dei Lanzi (also known as the Loggia della Signoria), a famous arcade used for the display of antique and Renaissance sculpture. Just visible within the narrow street beyond is the Uffizi gallery, whilst situated in the foreground are the equestrian statue of Cosimo I de’Medici by Giambologna (1529–1608), and the Fountain of Neptune by Bartolomeo Ammannati (1511–1592). Turner has exercised his usual economic approach within the drawing and, instead of fully delineating every detail of the Palazzo Vecchio, has simply noted the number of times the windows, crenellations and other architectural features are repeated along the façade.
