|This article does not cite any references or sources. (December
2007)| The Castello Plan is an early city map of Lower Manhattan
from 1660, created by Jacques Cortelyou, surveyor of then named-
New Amsterdam (later renamed by British colonial settlement as
New York City). Around 1667, cartographer Joan Blaeu bound the
plan, together with other hand-crafted New Amsterdam depictions,
to an atlas, which he sold to Cosimo III de' Medici, Grand Duke
of Tuscany. This transaction most likely happened in Amsterdam,
Netherlands, as it has yet to be proven that Blaeu had ever set
foot in New Netherland. It is covered extensively in volume 2 of
I. N. Phelps Stokes' six-volume survey The Iconography of
Manhattan Island. See also  - Iconography of Manhattan Island
