In Dorsoduro, not far from Squero San Trovaso, there's a canal called the Rio delle Ermite.
While walking along the fondamenta there, I found this set of green doors.
Really, I wasn't paying much attention to things on that side of the fondamenta - I was looking at the boats in the canal, but something caught my eye.
Upon further inspection, I noticed that the green doors had handles fashioned out of forcolas.
Here's a close-up of one of the "handles": I don't know who the remer was,
or how much the owner spent,
but whoever did this definitely gets props from me.
