In 2026, We the Italians celebrates “Two Anniversaries, One Heart” – the 250th anniversary of the United States and the 80th anniversary of the Italian Republic. This article is part of the “Happy Birthday USA: Unsung Italian Heroes” project, in which we share how, in every corner of the United States, an Italian has made a positive impact on their local community.

Dominic Altieri, carving out a monumental role in a new world

For over 125 years the traditions of southern Italy have profoundly shaped the character of Westchester County’s architecture and landscape, most prominently witnessed in stucco building façades, public works of stone, and a wide spectrum of natural enhancements. 

Consider the Hudson River town of Dobbs Ferry. In 1885 a mere six Italians resided there, while by 1920 the village population, which had more than doubled, was 60% southern Italian immigrants from the province of Avellino in Campania who had made the town their home. Many of the new arrivals settled on Main and Palisade Streets, where they re-created hilltop piazzas, gardens and stucco dwellings reminiscent of their former homeland. Houses made of clapboard were covered with stucco, stone retaining walls were constructed, fig trees were planted and backyard shrines erected.

An impressive reinterpretation of southern Italian vernacular architecture can be seen in the work of Dominic Altieri, a stonemason from the village of Bovino, who settled in Dobbs Ferry and infused the memories of his birthplace in the design and construction of his family’s home—the “house of his dreams,” according to his daughter, Val Coletti—on Main Street. It’s an inviting four-story dwelling with a distinctive façade of stonework porticos and porches; town residents referred to it as “the Palazzo.”

Shortly afterward, in 1923, Altieri would build a replica of the cathedral in the Avellino hilltop village of Calitri, using stone from area quarries. Our Lady of Pompeii Church still stands on Palisade Street, as does his “Palazzo” on Main, an enduring testament to the Altieri legacy.

Less than 15 miles north of Dobbs Ferry one can hear the refreshing sounds of waterfalls and enjoy the magnificence of the New Croton Dam, an area landmark. Far more than an extraordinary feat of civil engineering inspired by Roman ingenuity, it’s a place layered with history and grandeur. Its story was largely shaped by the hands of Italian stonemasons who settled in the Hudson River towns of Dobbs Ferry, Ossining and Croton-on-Hudson (as well as neighborhoods in lower Manhattan and the Bronx).

Completed in 1906, the new dam and water transport system was designed to address the rapidly increasing demand for clean water in New York City. The dam stands 300 feet high; the 150-foot deep water system ran for 33-miles and required precise stone-cutting and placement to withstand the pressure of 19 billion gallons of water. Their construction took fourteen years of arduous and perilous labor. At the time of its completion, the dam was the tallest in the world!

Westchester’s New Croton Dam stands as not only a great feat of engineering but also a monument to the immigrant labor that made it possible. Although the over 2000 Italian masons who were the backbone of its construction were never formally credited, their work shaped the infrastructure that helped New York City thrive. Today, their legacy lives on not just in historical records but in the enduring and imposing presence of the dam itself. In 1978, the New Croton Dam was officially added to the National Register of Historic Places, a lasting tribute to the skill, sacrifice, and endurance of those who built it.
