Before the arrival of European settlers in the 17th century, the area now known as Manhattan was inhabited by the Lenape people, who called the island Mannahatta. The island’s landscape was then characterized by wetlands, forests, and beaches. Connected by a trail called Wickquasgeck, this path linked Lenape village sites across the island, shaped largely by the natural terrain, according to Joe Baker, executive director of the Lenape Center.

With the arrival of Dutch settlers in the early 1600s, the trail was widened and renamed Brede Wegh, meaning “broad way” in Dutch. After the British took control of the area in 1664, the route eventually became known as Broadway. Despite its current prominence, Mr. Baker noted that for many Lenape, Broadway symbolizes displacement and invisibility, reflecting the broader history of indigenous exclusion tied to colonialism.

Today, Broadway extends from Lower Manhattan northward into Westchester County, retaining segments that follow the original line of the Wickquasgeck trail, said Michelle Young, author of a recent history of the street. Unlike Manhattan’s sharply grid-like streets such as Madison Avenue and Fifth Avenue, Broadway runs diagonally through Midtown, a path that predates the city’s 1811 grid plan.

This diagonal trajectory has contributed to the creation of several major public spaces, including Union Square, Madison Square, and Times Square. Ms. Young highlighted these areas as important venues for social movements across the United States, underscoring Broadway’s ongoing role as a public gathering place.

The street’s distinctive, irregular course serves as a subtle reminder of Manhattan’s original natural landscape, offering a contrast to the otherwise uniform urban grid. Ms. Young suggested that without Broadway’s unique alignment, New York City’s streetscape might feel less human and more rigidly designed.

Broadway thus remains not only a central thoroughfare in New York City’s layout but also a living historical record of the island’s transformation—from indigenous land and trails, through European colonization, to its current status as a cultural and urban landmark.
