In our next to last look at some interiors and the Medici arms they contain, I believe that all of the following come from the Palazzo Vecchio (literally, Old Palace), the town hall of Florence. It is now a museum, and well worth the visit, even if you aren't looking for Medici coats of arms!
Did you find any armorial decorating ideas in any of the above pictures? I know I did! (If only I could afford them now.)
