Despite its clear military advantage, and despite the knowledge of city planning, the New World settlements of the Spanish actually grew amorphously for some three to four decades before they turned to grids and city plans as ways of organizing space. In contrast to the orders given much later on how the city should be laid out, Ferdinand II did not give specific instructions for how to build the new settlements in the Caribbeans.
