The Letters of Philip II, King of Spain, 1592-1597 a digital collection available within the Special Collections Department of the Harold B. Lee Library, Brigham Young University, Provo, Utah, USA, is made of "... 174 Letters and documents, all in Spanish : 172 manuscript, 2 printed.
Although Venice is composed of islands and canals, the Grand Canal is the only really large one. It's shaped like a backwards letter S, and is approximately two miles long. At its widest point, at the Salute/San Marco (southern) end, it is roughly 350 feet wide; the normal width is about half that.
I found this site to give me alot of information about the grand canal and how the people lived at the time. I would recomend this site to you if you are doing the grand canal.
