The map titled "Plan of part of the River Delaware from Chester to Philadelphia" was created by John Hunter in 1778. It provides a detailed view of the Delaware River, marking the positions of British ships on November 15, 1777, during the American Revolutionary War. The map also highlights obstructions placed in the river by American rebels to impede navigation, such as chevaux de frise (obstacles designed to damage ships). Additionally, it includes soundings to indicate water depths and other strategic details relevant to the military operations of that time.

The Map of City of Brooklyn, a detailed map of Brooklyn and the village of Williamsburg, created by Matthew Dripps in 1850, provides valuable historical information about the development of Brooklyn in the mid-19th century. It illustrates the streets, coverage of buildings, displays numbered wards, and lot lines. The map also includes illustrations showing major public buildings of the city at the time such as Kings County Prison, Naval Asylum and the City Hall. An important resource for anyone interested in the history of Brooklyn, it was hand-colored to highlight ward boundaries, and was originally printed on two sheets, one for the western portion of the city and one for the eastern portion.

Prior to New York City's Commissioners' Plan of 1811, the city's Common Council in 1797 commissioned city surveyors Casimir Goerck and Mangin to survey the streets of the city; Goerck died of yellow fever during the course of the surveying, but Mangin completed it and delivered the draft of the Mangin–Goerck Plan to the Council in 1799 for correction of street names; the final engraved version would be presented to the Council in 1803. Unfortunately, Mangin had gone beyond the terms of the commission, and the map not only showed the existing streets of the city, but also, in Mangin's words, "the City ... such as it is to be..." In other words, the plan was a guide to where Mangin believed future streets should be laid out.The Council accepted the Mangin–Goerck Plan as "the new Map of the City" for four years, and even published it by subscription, until political machinations perhaps organized by Aaron Burr, the political enemy of Mangin's mentor Alexander Hamilton, brought the plan into disrepute, and the Council ordered that copies which had already been sold be bought back, and that a label warning of "inaccuracies" be placed on any additional copies sold. Nevertheless, as the city grew, the Mangin–Goerck Plan became the de facto reference for where new streets would be built, and when the Commissioners' Plan was revealed in 1811, the area of the plan which the public had been warned was inaccurate and speculative, had been accepted wholesale by the commission, their plan being almost identical to Mangin's in that area.

Map made by Adriaen Block of his 1614 expedition to North America. It is the first map to show Long Island as an island. It is also the first appearance of the term New Netherland to describe the colony (17th century drawing).

This map, titled "Plan of the City of New York in North America," was published in 1776 by Bernard Ratzer and engraved by Thomas Kitchin. Surveyed in 1766-67, it includes detailed information about parts of present-day New York City - Manhattan below 60th Street, Brooklyn north of 30th Street and west of Union Avenue, a small part of modern Queens and Jersey City, New Jersey. It depicts built-up and cultivated areas, streets, rural roads, buildings, piers, streams, ponds, wetlands, relief by hachures, and depths by soundings. It also has a dedication to Sir Henry Moore, the then Governor of New York, and a key to various churches and public buildings. Additionally, it comprises a southwest view of the City of New York, taken from the Governors Island, based on a work by Thomas Davies.

 The print contains 18 small views: High Bridge ; South Ferry ; City Hall ; Castle Garden ; Croton Reservoir ; Grace Church ; Institution for the Blind ; Post Office ; Merchants Exchange ; Astor-Place Opera-House ; Barnum's Museum & Astor Hose ; Halls of Justice (Tombs) ; Bowling Green ; Astor Library ; Custom House ; Odd Fellows Hall ; University ; Trinity Church.

The map of New York City and Manhattan, created by the commissioners appointed by the legislature and surveyor William Bridges, depicts ward boundaries, significant buildings, and the names of property owners. It is oriented with north towards the upper right and includes numbered references to various locations within the city. Often referred to as the "single most important document in New York City's development," the map was praised by the commission for its combination of "beauty, order and convenience" due to its use of the grid plan.

1st map to show all NY lots & buildings. The precursor of the fire maps was first published by Perris in 1852, and later, it was published by Sanborn and Bromley. This is the 2nd edition. The border has views of important city buildings.

The Mannahatta Project was an urban ecological study to imagine what Manhattan would be like if there were no settlers.  

John Montresor’s map titled “A Plan of the City of New-York & its Environs” is a significant historical document created in 1766. This detailed map covers the area from Greenwich on the North or Hudsons River to Crown Point on the East or Sound River, showcasing the layout of streets, public buildings, docks, fortifications, and batteries. It also depicts the topography and strategic commanding grounds in and around the city.The map is notable for its scale, approximately 1:6,300, and includes an inset chart showing the entrance to New York from Sandy Hook, highlighting the best channels for sailing along with the banks and depths of water. It was dedicated to the Honorable Thomas Gage and provides a fascinating glimpse into the urban landscape of New York City during the mid-18th century, just before the American Revolution.Montresor was an engineer, and his work reflects the military and strategic importance of New York at the time, with relief shown by hachures and a clear indication of the city’s defenses. The map is part of the collection at the Library of Congress and is a valuable resource for historians and anyone interested in the early cartography of New York City.

Chandler view of New Amsterdam in 1660: the present southern end of Manhattan Island, New York City

Lower Manhattan has effectively been America’s town square since its discovery in 1524. Virtually every major event of local, national and global significance has played out in some way on this stage. Some have been forgotten and some have been transformative in our culture and many have fallen between. This is both a project in urban archeology and a way of describing the city over time in a printed map. The map captures the multiple and overlapping stories that are woven throughout our city’s life in a single document. It embraces America’s history as the museums, monuments and memorials that dot its streetscape do.   It highlights many of the concerns, events and places that the people who lived, fought, worked and visited here thought were important at their moment in time.   It takes another look at the issues that they were preoccupied with and how they solved them:  their politics, religion, social protest, health and safety, commerce, disasters and defense, scandals and crime, education, publications, art and culture, parades and celebrations, architecture and engineering. It encapsulates the events that shaped the physical and cultural landscape within the changing geography at the water’s edge. And it raises questions that need to be considered as we plan a more resilient city in our future.  

The Castello Plan of New Amsterdam is a map of the early Dutch settlement of New Amsterdam, which later became New York City. The map was created in 1660 by Jacques Cortelyou, General Governor of Nieuw Amsterdam at that time, and is one of the earliest surviving maps of New Amsterdam. The map shows the layout of the settlement, including the locations of streets, buildings, and fortifications. It also includes illustrations of various landmarks and features of the city, such as the town hall, the church, and the governor's house. The Castello Plan is an important historical document as it provides a detailed record of the early development of New Amsterdam and is one of the few surviving primary sources from this period of the city's history. It is now housed in the New York Historical Society in New York City. It was discovered in 1900 at the Villa di Castello near Florence, Italy, where it had remained. Shown here is the version that was redrawn by John Wolcott Adams and Isaac Newton Phelps Stokes, and given its current name in 1916.
