You could be forgiven for walking right past this church, and not noticing it. It is in the Campo Maddalena, which is located off the Strada Nova, just near the bridge which crosses the Rio della Maddalena. It’s rarely open, you might be lucky to find an art display there during Biennale, or Nativity scenes (presepe) around Christmas. The bell shown below looks a bit rusty, but the ropes seem in good condition.
If you do happen to take a little detour to check out this building, take note of the motif above the door, as seen in this image from Wikipedia. It is reminiscent of a Masonic symbol.
