Isola di San Michele
This island is marked blue on the map, suggesting it belongs to the Castello Sestieri.

However, the island's wiki page, starts out saying:
 * San Michele is an island in the Venetian Lagoon, northern Italy. It is associated with the sestiere of Cannaregio, from which it lies a short distance northeast.

So, which is it? Is the island associated with Castello (blue) or Cannaregio (purple)?
