Trowbridge Square Park

Trowbridge Square Park is a small public green space located in the Hill neighborhood of New Haven, Connecticut. The park serves as the centerpiece of the Trowbridge Square Historic District, which was listed on the National Register of Historic Places in 1985.

Originally known as Spireworth Green when the area was first laid out in 1830, the park was later renamed Trowbridge Square after Thomas R. Trowbridge, a prominent local developer who funded improvements to the park in the 1850s. The square was designed as part of a planned working-class residential area, modeled after New Haven's central Nine Squares plan.

The park is roughly bounded by Cedar Street, Carlisle Street, and Portsea Street. It provides a quiet, open green space in the heart of the historically working-class neighborhood. The surrounding streets feature modest 19th-century houses that reflect the area's development as a home for laborers and immigrants, particularly Irish and Italian families in the late 1800s and early 1900s.

While small in size, Trowbridge Square Park continues to serve as a gathering place for local residents and a reminder of the neighborhood's rich history as one of New Haven's early planned communities outside the city center.
