Map of Ansonia, Connecticut in 2026

If you grew up in Ansonia, or you’ve ever walked Main Street past the old opera house, you’ll find your city on this map just as it stands in 2026. Look for your street. Main Street, North Main Street, Bridge Street, Elm Street, Maple Street, Jewett Street, Division Street, Wakelee Avenue, Prindle Avenue, Byron Avenue, Great Hill Road, Colony Road, Scotland Street and Pulaski Highway are all printed by name, along with dozens more.

Ansonia is in New Haven County, Connecticut, on the Naugatuck River just north of Derby.

KNOWOL made this map in 2026 from public survey data, and gave it the look of an old atlas. The shaded hills around downtown and Derby Hill come from United States Geological Survey elevation data, and the streets and the city line come from the Census Bureau. Houses sit in their proper places. A guide of 34 numbered landmarks runs along the bottom, with the four National Register sites marked, and we checked those against National Park Service records.

How Anson Phelps Gave Ansonia Its Name

English colonists first settled along this stretch of the Naugatuck River in 1652, when the land was part of Derby. Farmers used the river for sawmills and gristmills. Then in 1844 the merchant Anson Green Phelps bought land on the east bank of the river and started an industrial village. A canal was dug to bring river power to the new factories. On a friend’s suggestion, Phelps used his own first name as the root for the village’s name, and it became Ansonia.

The Ansonia Clock Company was founded here in 1851. Ansonia came to be called the Copper City, for its copper and brass mills, and its factories also turned out rubber, iron castings, sheet metal, electrical goods and textiles. The village kept growing, and in 1889 the General Assembly let it separate from Derby as a town of its own. That’s the year on the title panel of the map: Incorporated 1889. Ansonia became a city four years later, in 1893. Click here to learn more about the history of Ansonia.

Downtown and the Opera House

The tight cluster of numbers in the middle of the map is downtown Ansonia, the land Phelps bought on the east side of the river. Part of Main Street there is the Upper Main Street Historic District (32), on the National Register of Historic Places. Its best-known building is the Ansonia Opera House (26), built about 1870 in the Italianate style, in brick and stone.

Ansonia City Hall (7) is downtown, along with the United States Post Office-Ansonia Main (17), which is on the National Register too. The Ansonia Police Department (13) works out of the renovated former headquarters of the Farrel Corporation on Main Street, once the world headquarters of a leading maker of rubber and plastics machinery. The Ansonia Library (5) has served the city since 1896, and the Valley YMCA (3) and Christ Church (4) are a short walk away. Ansonia Station (22) is a stop on Metro-North’s Waterbury Branch, which connects to Grand Central Terminal in New York, and the Ansonia Riverwalk Park (27) is close by.

The Humphreys House and the Mansfield House

The General David Humphreys House (15) stands at 37 Elm Street, south of downtown, and it was added to the National Register in 1972. In 1690 the town of Derby voted to build a house for its minister, and this one was finished in 1698. David Humphreys was born here. He served as an officer in the Revolutionary War and as George Washington’s aide-de-camp, and he became our nation’s first ambassador. Today the house is a museum and the headquarters of the Derby Historical Society, which serves Ansonia too.

The Richard Mansfield House (12), at 35 Jewett Street, joined the National Register in 1971. It looks just as it did in 1747, when eight Episcopalian families bought it. Rev. Mansfield went on to serve the longest Episcopalian pastorate in the country’s history, 72 years, through the colonial, Revolutionary and federal eras. The house is privately owned today.

Churches, Schools and Parks

Ansonia’s churches fill a good part of the guide: the First Baptist Church (8), Christian Life Fellowship (11), First United Methodist Church (14), Assumption Church (25), the Ansonia Church of Christ (28), the Church of the Resurrection (29), Apostolic Refuge Tabernacle (30) and the Evangelical Temple Church of God (31). Chùa Phước Long (23) is northwest of downtown.

The schools include Ansonia High School (9) and Ansonia Middle School (10) to the south, Mead School (18), Prendergast School (24) and Emmett O’Brien Technical High School (33). For a day outside there’s Linnett Park (1), Warsaw Park (2), Nelligan Park (19), Pine Lot Fields (20), Abe Stone Park (21), City Open Space (6) and the Ansonia Nature and Recreation Center (16), which keeps open fields and woods up on Hilltop. Up in the northeast, the Naugatuck State Forest – Quillinan Reservoir Block (34) reaches into town.

This map of Ansonia makes a handsome addition to a living room, office, library or den, and it can even help teach children the geography and history of the city. It’s a thoughtful gift for anyone who calls Ansonia home, grew up here, or moved away. Created by KNOWOL in 2026, it’s printed on museum quality archival paper in three sizes.
