There is an update on the Palazzo Vecchio post on March 29th the picture is now attached. It is a picture of the brick and rib ceiling considered a monument to architecture. It was constructed in the 13th century. Very amazing when you think about the tools available to the builders of that time period. There were no cranes to lift bricks in place, wooden structures had to be built around everything stone while the masons put the bricks in place. Astonishing, when you think about it.
