English colonists first settled this stretch of the Naugatuck Valley in 1652 as part of Derby township. Exactly when Ansonia became its own town is disputed: the borough was chartered in 1864, while the National Register district record and other accounts date the full separation from Derby to 1889 — all agree the city followed in 1893. The name honors merchant Anson Greene Phelps, who wanted to call his mill village "Phelpsville" until he learned the name was taken and used his own first name instead. In 1844 Phelps bought land along the Naugatuck and dug a canal to power his factories, launching a run as the "Copper City" that also produced brass, rubber and plastics. The Ansonia Clock Company, founded here in 1851, later sold its machinery to a Soviet trading company in 1929, seeding the USSR's own clock industry. French mechanic Pierre Lallement road-tested an early bicycle patent on Ansonia's streets in 1866.

David Humphreys — aide-de-camp to George Washington and later U.S. Minister to Spain — was born July 10, 1752 in what was then Derby and is now Ansonia; in 1802 he imported merino sheep from Spain and founded the first successful woolen mill in the United States. The Ansonia Clock Company, a Phelps subsidiary founded in 1851 with Bristol clockmakers Theodore Terry and Franklin C. Andrews, moved most production to Brooklyn in the late 1870s; in 1929 its remaining machinery and tooling were sold to the Soviet trading company Amtorg and shipped to Moscow, where they seeded the Poljot and Sekonda clock brands. Pierre Lallement, a French carriage maker, demonstrated his pedal-driven "boneshaker" velocipede on the roads of Ansonia and New Haven before receiving a U.S. patent on November 20, 1866. The Upper Main Street Historic District, listed on the National Register on December 2, 1982, is a row of Classical Revival and Italianate commercial buildings from 1870-1900 centered on the Ansonia Opera House of about 1870.

Getting there

Ansonia sits directly on Connecticut Route 8, about ten miles north of I-95 in Bridgeport; the highway meets the Merritt Parkway in Trumbull and Interstate 84 at Waterbury's Mixmaster interchange. Route 34 interchanges with Route 8 just south of Ansonia and runs southeast toward Derby and New Haven. Metro-North's Waterbury Branch has a real Ansonia station at 40 West Main Street, between Derby-Shelton to the south and Seymour to the north — but travelers should know that buses replace all Waterbury Branch rail service from July 20, 2026 through May 31, 2027, part of a $29.2 million platform-reconstruction program; Ansonia's new 350-foot canopied platform is due to open in June 2027. CTtransit New Haven's Route 255 bus connects Ansonia station to New Haven. There is no Amtrak, Shore Line East or CTrail Hartford Line service in Ansonia; the nearest is New Haven Union Station.

Frequently asked questions

How do I get to Ansonia?
By car on Connecticut Route 8, which meets the Merritt Parkway in Trumbull and I-84 at Waterbury. Ansonia has a Metro-North Waterbury Branch station at 40 West Main Street, but buses currently replace all rail service on the branch from July 20, 2026 through May 31, 2027 while the platform is rebuilt — do not plan to arrive by train until the new platform opens in June 2027.
Is Ansonia's incorporation year 1864 or 1889?
Sources disagree. Connecticuthistory.org gives 1864, the year the borough was chartered; the National Register district record and other accounts date the town's full separation from Derby to 1889. Every source agrees Ansonia reincorporated as a city in 1893.
