Arch Street in New Britain preserves buildings from the turn of the twentieth century that reveal both the city’s architectural development and its long role as a center of community life and social services. The street includes examples of Italianate and Beaux Arts architecture, including 180 Arch Street and 191 Arch Street, and prominently features the work of architect William H. Cadwell, whose designs included 59 Arch Street, formerly the Vega Society Benefit Hall, and 191 Arch Street; his own Châteauesque home stood nearby at 130 West Main Street. The Vega building, built in 1897, is noted for yellow brick, terracotta accents, stained glass windows, and intricate molding. At Arch and Grand Streets, the New Britain Armory, designed by Robert Wakeman Hill in 1886, was later renovated for housing in 1992 after the state abandoned it, though its central tower’s dome was never replaced. In the late 1990s, ornamental paving, lighting, trees, and other streetscape elements were added along Arch Street, and at the turn of the twenty-first century the Friendship Service Center added a new building. In the late nineteenth century, fraternal organizations and cultural clubs, including the city’s Turner Society and the Vega Benefit Society, settled on Arch Street and provided social, cultural, and practical support, especially for immigrants, becoming central to working-class neighborhood life. New Britain also developed as a regional social services hub, with Arch Street hosting such efforts for over a century; the Salvation Army was located there from the 1920s through the early 1960s, and the Friendship Service Center, founded in 1968 by Monsignor Joseph Farrell, moved to 241 Arch Street in 1992 and now operates from three street locations, including the Vega Building. Advocacy for Arch Street dates to at least the 1880s, and in recent years a Latino neighborhood has emerged there, continuing the street’s long tradition of ethnic cultural continuity and community.
