This Clever Map is a Window into 19th Century New York City
The early 19th century was a time of great change for New York, which had already cemented its status as America’s largest city.
The opening of the Erie Canal helped turn the city into a shipping powerhouse, and there was a building boom on the horizon. Cholera epidemics, fires, and riots swept through the city at various points.
This fascinating interactive map, from Esri, is a snapshot of New York City during the tumultuous time (1836 to be exact), overlaid on the modern-day satellite map.
Getting the Lay of the Land
The base map used above is the stunning “Topographical Map Of The City and County Of New–York, and the adjacent Country”, published by the prodigious mapmaker, Joseph Colton.
For easy viewing, the map’s legend is below:
This map includes all the usual features, such as roads and prominent buildings, but it also has some clever secondary information built in as well. For one, shading indicates ares that were more built-up at the time. There are also a number of visual techniques to indicate topographical features as well. After all, NYC wasn’t as extensive as it is today, and much of the land depicted in the map is still undeveloped.
The full map is well worth exploring as well, as there are a number of beautiful illustrations throughout.

The Big Picture: New York City in 1836
At this point in time, development in Lower Manhattan extended until about 14th Street, where buildings began to give way to open spaces. The city’s grid pattern was beginning to take shape, following the Commissioners’ Plan laid out in 1811. At the time, New York was anticipating massive growth, and the straightforward grid pattern was an efficient way to prepare the city for rapid expansion.
In the 1800s, fire was an ever-present danger for city dwellers. In fact, a major fire tore through Lower Manhattan a year prior to when this map was published.
Points of Interest
There are a number of points worth visiting on this map.
Transit Begins to Take Shape
In the 1830s, New York City’s first railroad line—horse powered for its first few years—connected Prince Street to the Harlem River, accelerating the city’s expansion northward from Lower Manhattan. This route is still recognizable today as the Harlem Line.
Evolving Shorelines
One very obvious difference between the two maps is how much land has been reclaimed along shorelines in the area. Battery Park City, on the west side of downtown, and the Brooklyn Navy Yard are two prominent examples of infill. Randall’s Island, located near the top of Manhattan, is also an interesting place to observe changes in topography. Randall’s Island is actually made up of three islands that were eventually conjoined in the 1960s.
This interactive map is a great place to explore changes to NYC’s shoreline over time.
Taming the Landscape
Midtown Manhattan is worth zooming into for a couple of reasons. First, the outline of Central Park is visible, although the park would officially be approved until almost 20 years later.
As well, this topographical map clearly shows the numerous outcroppings spread across the island. Manhattan was far from flat in the 1800s, and it took a tremendous amount of effort—starting with gunpowder, pickaxes, and horse-drawn carts—to level the land.
Looking at these historical maps is a reminder that the New York City we know today is the product of hundreds of years of human effort, and that cities continue to evolve over time.

The Incredible Historical Map That Changed Cartography
Check out the Fra Mauro Mappa Mundi (c. 1450s), a historical map that formed a bridge between medieval and renaissance worldviews.
The Incredible Historical Map That Changed Cartography
This map is the latest in our Vintage Viz series, which presents historical visualizations along with the context needed to understand them.
In a one-paragraph story called On Exactitude in Science (Del Rigor en la Ciencia), Jorge Luis Borges imagined an empire where cartography had reached such an exact science that only a map on the same scale of the empire would suffice.
The Fra Mauro Mappa Mundi (c. 1450s), named for the lay Camaldolite monk and cartographer whose Venetian workshop created it, is not nearly as large, at a paltry 77 inches in diameter (196 cm). But its impact and significance as a bridge between Middle Age and Renaissance thought certainly rivaled Borges’ imagined map.
One of ‘the Wonders of Venice’
Venice was the undisputed commercial power in the Mediterranean, whose trade routes connected east and west, stretching to Flanders, London, Algeria, and beyond.
This network was protected by fleets of warships built at the famous Arsenale di Venezia, the largest production facility in the West, whose workforce of thousands of arsenalotti built ships on an assembly line, centuries before Henry Ford.

The Mappa Mundi (literally “map of the world”) was considered one of the wonders of Venice with a reputation that reached the Holy Land. It is a circular planisphere drawn on four sheets of parchment, mounted onto three poplar panels and reinforced by vertical battens.
The map is painted in rich reds, golds, and blues; this last pigment was obtained from rare lapis lazuli, imported from mines in Afghanistan. At its corners are four spheres showing the celestial and sublunar worlds, the four elements (earth, air, fire, and water), and an illumination of the Garden of Eden by Leonardo Bellini (active 1443-1490).
Japan (on the left edge, called the Isola de Cimpagu) appears here for the first time in a Western map. And contradicting Ptolemaic tradition, it also shows that it was possible to circumnavigate Africa, presaging the first European journey around the Cape of Good Hope by the Portuguese explorer Bartolomeu Dias in 1488.
NASA called the historical map “stunning” in its accuracy.
A Historical Map Between Two Worlds
Medieval maps, like the Hereford Mappa Mundi (c. 1300), were usually oriented with east at the top, because that’s where the Garden of Eden was thought to be. Fra Mauro, however, chose to orient his to the south, perhaps following Muslim geographers such as Muhammad ibn Muhammad al-Idrisi.
Significantly, the Garden of Eden is placed outside of geographic space and Jerusalem is no longer at the center, though it is still marked by a windrose. The nearly 3,000 place names and descriptions are written in the Venetian vernacular, rather than Latin.
At the same time, as much as Fra Mauro’s map is a departure from the past, it also retains traces of a medieval Christian worldview. For example, included on the map are the Kingdom of the Magi, the Kingdom of Prester John, and the Tomb of Adam.

The circular planisphere also follows the medieval T-O schema, first described by Isidore of Seville, with Asia occupying the top half of the circle, and Europe and Africa each occupying the bottom two quarters (Fra Mauro turns the ‘T’ on its side, to reflect a southern orientation). Around the circle, are many islands, beyond which is the “dark sea” where only shipwreck and misfortune await.
Fra Mauro’s Legacy
Fra Mauro died some time before 20 October 1459, and unfortunately his contributions fell into obscurity soon thereafter; until 1748, it was believed that the Mappa Mundi was a copy of a lost map by Marco Polo.
In 1811, the original was moved from Fra Mauro’s monastery of San Michele to the Biblioteca Nazionale Marciana, following the suppression of religious orders in the Napoleonic era, where it can be viewed today.
Two digital editions have also been produced by the Museo Galileo and the Engineering Historical Memory project, where readers can get a glimpse into a fascinating piece of cartographic history.
