Gardens in Venice

From my Venice trip last September.
The top one was in San Marco, facing the Grand Canal, between the Rialto and the Accademia Bridges.
The one on the left was outside a church in Castello, near the Fondamente Nuove.
The one in the middle was right near the Ca D'Oro, just to the left of it.
And the one on the right was outside the Alloggi Alla Scala - remember the little hotel?
