1. A picture of Brunellesschi's cupola del duomo (cathedral dome) on the Cathedral of Florence, an engineering marvel.
2. The Ponte Vecchio bridge, the oldest bridge in the city, built as it is now in 1345. The little row of houses on either side are jewelry (mostly gold) shops.
Above the houses, on the upstream side of the bridge, is Vasari's corridor, built by Vasari so Cosimo could go from Palzzo Pitti to Palace Vecchio, a "secret" corridor.
A local pharmacy, note the old sign .
