How a Manhattan Potter's Field Transformed into a Theatrical and Commercial Powerhouse

Cultures · Published 9 October 2026 Swipe more like this →

In short: Union Square began as a humble intersection of two roads, eventually evolving into a bustling theater district, a hub for department stores, and a site of profound historical significance. From its origins as a potter's field to its modern status as a National Historic Landmark, the square reflects New York's relentless transformation.

In the early 19th century, the area now known as Union Square was a potter's field. When city surveyors planned the grid for Manhattan, the intersection of Broadway and the Bowery created an awkward angle that was difficult to develop. To resolve this, officials designated the space as a public commons in 1815. By 1831, developer Samuel Ruggles successfully lobbied to rename the area Union Square, expanding its boundaries and transforming it into a rectangular park that opened in 1839.

By the late 19th century, the neighborhood had become the center of New York's first commercial theater district, known as the Rialto. As the city expanded, the area shifted from residential mansions to a commercial hub, attracting department stores like S. Klein and Ohrbach's. However, the district's fortunes fluctuated; by the 1920s, the area faced decline, characterized by shoddy businesses and tenements. The construction of the 14th Street–Union Square subway station in the early 20th century further reshaped the landscape, requiring significant excavation and park renovations.

The late 20th century marked a period of revitalization. Following the closure of major retailers like S. Klein in 1975, the area saw new investment, including the Zeckendorf Towers. A major refurbishment in the 1980s addressed issues with vandalism and drug use, helping to restore the park's appeal. Today, the square is recognized as a National Historic Landmark, celebrated for its role as the site of the first Labor Day parade and its enduring collection of statues, including those of George Washington and Abraham Lincoln.
