The churches of Castello
There are 27 churches in this sestiere; only Cannaregio (with 32) has more.
San Zaccaria is a must because of its drop-dead gorgeous Bellini altarpiece, but there’s much else to see including a nice gothic chapel and a crypt that you can visit if it’s not full of water.
Another favorite is San Francesco della Vigna with its beautiful Madonna (see left) by the Franciscan friar Antonio da Negroponte, another mysterious artist. This is his only known painting. If you’re only going to bat once, you might as well knock it out of the park as he did. I also love Cima da Conegliano's Baptism of Christ that's on the high altar of San Giovanni in Bragora.
San Giorgio degli Schiavoni is a former scuola and church that’s now a museum; it contains some of my favorite paintings in Venice – the Carpaccio cycle which includes St. George and the Dragon and St. Augustine in his Study (the saint’s dog must be the cutest dog ever painted).
Chorus Pass churches in this sestiere are San Pietro di Castello and Santa Maria Formosa.

The Greek Orthodox cathedral with a leaning tower, this church is dedicated to San Giorgio (St. George), the charismatic dragon-fighting, princess-saving saint. 
A charming parish church with a couple of famous baptisms.
Before my trip, I read a sweet little book called The Other Venice by Predrag Matvejevic, recently translated from Croatian to English. It’s a dreamy, poetic book by a guy who obviously loves Venice very much and loves obscure details as much as I do. Nice black-and-white photos by Sarah Quill too. 

“I’m glad you found our angel,” he said, and proceeded to tell me the story. The Venetians stole the angel from Anatolia in Eastern Turkey, he said, and a family named Rizzo put in on the archway above the entrance to a sotoportego, along with the reliefs on either side. They don’t show up well in my photos, but the reliefs are porcupines (or maybe hedgehogs?), which was the insignia of this family. The man showed me the family’s palazzo which is one of the oldest in Venice (13th c.) and told me that the way to identify the oldest buildings is to look at the chimneys (the round ones are older than the more common tulip-shaped ones). 
I love the way the Venetians give nicknames to their churches. The real name of this church is Santa Maria della Consolazione but no one ever calls it that – it's known instead by its charming nickname which translates to Our Lady of the Fava Bean. 
On the façade of the church, there’s a bocca di leone (lion’s mouth) – these are the letter-boxes where Venetians could lodge complaints and report crimes, the Republic’s version of a crime stopper’s hotline, maybe?
This beautiful shrine commemorates a demolished church that used to be in this Castello campo. Founded in 1130, the church was originally dedicated to Saints Liberal and Alexis but was rededicated to Santa Marina when her body was placed on the high altar of the church in 1231 after the Venetians stole her from Constantinople. These "pious thefts" are strange and recurring events in Venice's history; for whatever reason, stealing the body of San Marco in 828 started a trend that continued for centuries.
