The map exhibits the development plan of the city of Manila showing neighborhoods by the Pasig River and across from Intramuros. The Philippines depended on the Spanish Crown from 1521, the date of the first settlement on the island of Cebu. More than two hundred new cities were founded along the archipelago with the traditional grid structure, but some with other urban typologies that were not implemented nor realized. In the beginning, they were mostly located on the coast and later became port cities, but the ensuing exploration of inland territories led to the construction of new settlements, later linked through a network of roads, railroads and navigational routes.
