Venice, Saint Mark's Square 4

Here we have the clock tower, one the more unique ones because the clock face has astronomical symbols on it. It's also a mechanical clock. The doors right above the clock face open automatically and an angel with a trumpet that actually plays comes out followed by three wise men. It's hard to see from this angel, but there's also a bell at the top, and two bronze shepherds alternate hitting it with hammers to chime the hours.
