Chiesa Santa Maria dei Miracoli is probably my favorite church in Venice. Surrounded by canals and small streets, the church looks like a fat piece of marble clad wedding cake that landed in Venice's Cannaregio neighborhood.
It's one of the most beautiful churches in all of Venice, especially after it underwent a 10 year and nearly 4 million dollar restoration by Save Venice Inc. Prior to the restoration, the church's marble work was so pregnant with salt from the lagoon air that it was on the verge of failing to bits. Built between 1481 and 1489 by Pietro Lombardo, the barrel-vaulted single nave church is one Venice's greatest (and smallest) architectural treasures.
